What are you guys talking about, there were 3,235 people at that game. It was nearly half full for a weekday game against a crap team, they were all just in the luxury seats to avoid the cold/on the concourse/tailgating or otherwise somewhere else that doesn't' appear in a picture or on TV.
Or, there was ~1500 people there and they sold 3235 tickets. Which is what Tulsa reported during the Wojick times (sometimes I could count the fans in the end days).
Anyway, Houston is good. But they need a serious branding effort in their hometown (again, so does Tulsa) to try and become "THE" team in town.
