Opinion By
Craig Dickey and Brenda Dickey appeal the summary judgment granted in favor of Club Corporation of America and Richardson Club, Inc. d/b/a Canyon Creek Country Club. 1 In two issues, the Dickeys contend generally that the trial court erred by granting the Club’s motion for summary judgment and by failing to sustain their objections to the Club’s summary judgment evidence. We overrule the Dickeys’ issues and affirm the trial court’s judgment.
Factual and Procedural Background
In 1990, the Dickeys joined Canyon Creek. Canyon Creek is one of many clubs owned and operated by Club Corporation of America. The Dickeys purchased a resident (full golf) family membership. Directly above the signature line on the membership agreement signed by Craig Dickey is the following statement: “The Undersigned agrees to conform to and be bound by the Bylaws and Rules and Regulations of [Canyon Creek], as they may be amended from time to time.”
At the time the Dickeys joined Canyon Creek, the bylaws provided that women could not obtain tee times before 1:00 p.m. on Saturdays and holidays, between 12:00 noon and 2:00 p.m. on Fridays, or before 10:00 a.m. on Sundays. Men could not obtain a tee time on Thursday mornings. In 1992, this policy was somewhat relaxed and women were allowed to obtain tee times on Sunday and Friday mornings. In 1996, the bylaws were amended to provide for the “gold/silver policy.” This policy does not contain the previous gender restrictions. Rather, it provides that each family must designate a gold member and a silver member. Only gold members may obtain tee times before 11:30 a.m. on Saturdays. Only silver members may obtain tee times before 12:30 p.m. on Thursdays. The only exception to this rule occurs when the course is reserved for special events such as golf tournaments. When the gold/silver policy was implemented, Canyon Creek informed its members by letter that each family was to designate a gold and silver member. The letter stated that, in the absence of a written designation, Canyon Creek would automatically designate the person in whose name the family membership was held as the gold member. The letter also stated that the designation may be changed by submitting the proper form.
In 1998, the Dickeys sued the Club for breach of contract and deceptive trade practices. The Dickeys claimed the Club breached its contract with them because the gold/silver policy in the bylaws conflicts with the membership agreement, which provides their joint membership is not divisible. According to the Dickeys, they are unable to play golf together on Saturday mornings under the terms of the gold/silver policy; therefore, one of the Dickeys is not entitled to the same privileges as the other and the bylaws have changed the meaning of “joint membership.” Further, the Dickeys alleged that the Club had engaged in deceptive trade practices because the Club’s actions were false and misleading. The Dickeys claimed that in 1996, when the gold/silver policy was implemented, the Club misrepresented that the membership agreement between it and the Dickeys allowed it to “unilaterally [change] ... the meaning of a joint membership.”
*175 The Club filed a motion for summary-judgment. In its motion, the Club alleged that it was entitled to summary judgment because: (1) the Dickeys agreed to be bound by the bylaws and rules and regulations of the Club; (2) the Dickeys’ claims are barred by limitations; (3) the Dickeys ratified the rule that is the basis of their claim; (4) the Club never misrepresented the rules that were in effect at the time the Dickeys joined the Club; (5) the Dickeys have not suffered any damages as a result of any act by the Club; (6) the Club is a private club and the courts should not interfere with how it chooses to manage its affairs; and (7) because the Dickeys continued to use the Club and enjoy its services for eight years after they learned of the eomplained-of rule, they are es-topped from asserting their claims. The Dickeys responded by arguing that: (1) the statute of limitations does not apply to their breach of contract claim because the contract is akin to a lease, and a new breach occurs each Saturday when the Dickeys are not allowed to play golf together; (2) the membership agreement does not permit the Club’s actions because the agreement does not allow the bylaws to fundamentally change the nature of the membership; (3) because the Club is not a private, non-profit club, it is not free from judicial scrutiny; (4) the representation by the Club that it had the right to unilaterally change the membership agreement by enacting the gold/silver policy was an illegal misrepresentation within the scope of the Texas Deceptive Trade Practices Act (DTPA); and (5) the doctrines of ratification and estoppel do not apply under these facts because the Dickeys protested the policy as soon as they discovered it and have continued to work against it the entire time they have been members of the club. The Dickeys also objected to the Club’s summary judgment evidence.
After a hearing, the trial court granted the Club’s motion for summary judgment without specifying the grounds upon which it based its ruling. The trial court also denied the Dickeys’ objections to the Club’s summary judgment evidence. This appeal followed.
Discussion
We review a summary judgment

to determine whether a party’s right to prevail is established as a matter of law.

Summary judgment for a defendant is proper only when the defendant negates at least one element of the plaintiffs theory of recovery or pleads and conclusively establishes each element of an affirmative defense.

Summary Judgment Evidence
Before addressing whether the trial court erred by granting the Club’s motion for summary judgment, we must examine the Dickeys’ claim that the Club’s summary judgment evidence was improper. As part of its supporting summary judgment evidence, the Club presented the affidavit of Ross Thornbrugh, Canyon Creek’s general manager. In his affidavit, Thornbrugh stated that he had personal knowledge of the facts contained in the affidavit. Thornbrugh also stated that he is the general manager of Canyon Creek. *176 The Dickeys contend that although Thorn-brugh’s affidavit contains a “rote recital that it was made on personal knowledge,” the facts contained within the affidavit show that to be untrue. According to the Dickeys, Thornbrugh did not become the general manager until September 1993, and thus he cannot have personal knowledge of any facts that occurred prior to that time.
We agree with the Dickeys that, to be sufficient, an affidavit must in some way affirmatively show how the affiant became personally familiar with the facts.

The Club’s Motion for Summary Judgment
In their first issue, the Dickeys contend generally that the trial court erred by granting the Club’s motion for summary judgment on their claims for breach of contract and for deceptive trade practices. Under this issue, the Dickeys set forth the same arguments raised in their response to the Club’s motion. We will address each of the causes of action in turn.
1. Breach of Contract
In its motion for summary judgment, the Club asserted, among other things, that it was entitled to judgment as a matter of law on the Dickeys’ breach of contract claim because as a private club, it has the right to make internal rules and regulations and to manage its affairs without judicial interference.
Traditionally, courts are not disr posed to interfere with the internal management of a voluntary association.
Harden v. Colonial Country Club,
*177 The Dickeys respond that these cases are distinguishable and the doctrine of non-intervention should not apply in this case because these cases involve nonprofit organizations and Canyon Creek is owned and operated by Club Corporation, a for-profit organization. We disagree. The summary judgment evidence shows that Canyon Creek, although owned and operated by a for-profit corporation, is nevertheless a social club with a voluntary, restricted membership. Canyon Creek’s facilities are available only to its members and their guests, not to the public at large. 2 Thus, we conclude that the policy of judicial non-intervention applies as well to Canyon Creek as to any of the private, voluntary organizations in the cases relied on by the Club.
The Dickeys make the conclu-sory statement that their “valuable property rights and civil rights are at risk because of the unilateral actions of the [Club];” however, the Dickeys do not specify what rights are at risk. Membership in a golf club is not a “valuable property right,” and the involvement of a property right alone does not necessarily authorize judicial intervention in the absence of arbitrariness, fraud, or collusion.
See Harden,
DTPA
With respect to the Dickeys’ DTPA claim, the Club asserted, among other things, that it was entitled to summary judgment because it had not committed any deceptive acts or practices. According to the Club, the Dickeys’ DTPA claim is merely a claim for breach of contract and without more, does not constitute a false, misleading, or deceptive act. We agree.
The Dickeys concede that a “mere breach of contract” does not make a deceptive trade practice.
See Crawford v. Ace Sign, Inc.,
Accordingly, we affirm the trial court’s judgment.
Notes
. For convenience, we will refer to Richardson Club, Inc. as Canyon Creek and to Club ' Corporation of America and Canyon Creek collectively as the Club.
. From time to time the facilities may also be used to host golf tournaments or other special functions.
. To the contrary, in their brief the Dickeys explained that they had determined that they did not have a cause of action for gender discrimination and, thus, have "not sued on constitutional or discrimination grounds. Instead, [we] have simply sued for breach of contract, because the Club never gave them the joint membership they bought, and for deceptive trade practices, because the Club deceived them about their rights and its responsibilities under that membership.”
