Have you considered contacting the Florida Cattlemen's Association? They should provide some guidance.
I have been in contact with the Professional Rodeo Cowboys Association Animal Welfare office - this St. Petersburg ordinance has appartently been in effect since before I was born. I had emailed the city council about quietly getting rid of it, and the St. Petersburg times found the story of a law student riding bulls to be newsworthy - so the cat is about to be let out of the bag. My goal here is to:
A) Continue work toward repeal of the St. Petersburg Rodeo Ordinance
B) Prevent the passage of any additional ordinances banning rodeo.
