If you go to Camden Yards make sure to walk on the street behind the outfield and look at the ground so you can see the little circles they put in the pavement where home run balls landed. They etch the name of the guy that hit it on them.

Houston's is pretty good, if you walk 3 or 4 blocks toward downtown you can get to quite a few bars. I once stayed at the Magnolia hotel downtown and my brother and a friend of ours walked to an Astros game and took the light rail down to see a Texans preseason game.
