Looking forward to my first baseball game

Tonight I am going to my first ever baseball game. I am seeing the Houston Astros play. I can't remember who they are playing against but to be honest I probably won't be able to tell who is who anyway. This is going to be more of an outing to experience American culture rather than me having any love for the game. I don't even know the rules.

It is supposed to be 100 degrees here today so I hope I don't die of heat exhaustion or anything. That would suck.
