There's been rumblings on the internet lately about Houston being the next expansion location.
They (so far) made it work in Vegas. Granted, Vegas is a special town, but their fanbase is loyal and certainly not only made up of out of towners. Houston has a built in fanbase of hockey fans; Aeros fans who were left torn after the team got forcibly moved to Iowa (I hold Norm Green/North Stars levels of hatred over that whole ordeal), and Houston is a major oil and gas hotbed, with employees relocated from many cities with NHL teams who would love for Houston to have a team.
The racial makeup of the downtown core is not what you would associate with ice hockey, but the Houston metropolitan area is f***ing massive. I don't think they would have a problem, and I can only hope that it happens, and that they are named the Aeros.
Arena wouldn't be a problem either, since there's already an NHL ready arena in town where the Rockets play; Toyota Center. Hell, the Aeros had 13,000 fans attend their last regular season game.
