Houston Rodeo Question

Hi, so this is my first time going to the rodeo and I’m trying to figure out at what time the rides close. I did see ticket sales end at 9:30. But like if I was to get there at least an hour early. Can we stay past 9:30? Mostly due to wanting to go with work friends but we all have our times everywhere so close to night time is our only choice but we’re trying to confirm if it’s possible to stay past 9:30. Thanks
