Roof, Roof, Roof for the Home Team
I've been to Houston. Twice. My sole purpose for setting foot there was to see games in the ball parks. Why on Earth else would anyone go there?

I saw two games in what was then aptly named Enron Field, now Minute Maid Park. They did a nice job incorporating the old Union Station into the ball park, but that's just a lobby that you walk through. The rest of the park, frankly, is rather plastic. The silly train above left field is one of the cheesiest things I've ever seen at a Major League ball park.
On Friday night, the game started with the roof closed, even though the late June evening was quite pleasant. Around the 6th inning or so, they opened the roof. No idea what the motivation was, or why it wasn't open the whole game.
The following afternoon was hot, but I didn't think it was uncomfortable.

Houston is a football town in a football state, and they think they get an advantage by playing in a noisy venue. With the tin roof closed, it's noisier. Again, this calls into question whether Houston deserves an MLB team.
"Bud" Selig has forced the Astros to play the World Series with the roof open, against their will. It's one of few -- if any -- decisions by the commissioner that I wholeheartedly agree with and endorse. Weather should be the only factor in deciding whether to close the roof.
The bottom line is that indoor baseball sucks.
