I'm originally from Ft. Worth and have gone to the Fat Stock Show since childhood. The public school system actually used to shut down for a day and all the school kids got free tickets to attend. It's no longer called the Fat Stock (politically incorrect).. I think the cows had their feelings hurt.
The badges, like yours, typically got you access to more of the events and parties. Kansas City does the same. The funny things is-- the F.W. Stock Show is actually going on right now. So it's a timely find. Enjoy!
