Where do season ticket holders hang out?

Are there specific bars or forums, etc where i can meet or reach out to season ticket holders? We built a new marketplace app (launching and testing in Houston) that let's buyers make guaranteed offers on seats. Basically an eBay or stockx for tickets. We think this will help STH with unsold and unused inventory- and now I want to get feedback to make sure we're solving the right problem.

Won't link anything here for promotion, just trying to have a few user conversations as we launch. Thanks in advance for any tips or convos!
