b) The operator must employ methods and procedures in coordination with the start of manning admission gates each day to conduct a thorough check of admission enclosure areas allowing only those persons to remain who produce tax exempt credentials of admission. All others shall be escorted to the gate and readmitted only through turnstiles on admissions subject to 40 cents state tax.

(Editor's Note: The Illinois Horse Racing Act of 1975 (Ill. Rev. Stat. 1979, ch. 8, par. 37-25) now provides for a 15 cents admission tax instead of 40 cents)
