Whether the Astros are making a World Series run (we miss you, 2005) or languishing in last place, you can have yourself a great night downtown at Minute Maid Park and not put much of a dent in your pocket at all. (We do advise filling up before the game, though; some tickets are cheap, but hot dogs and drinks are another story.) There's always a slew of great offers on the team's Web site: Maybe it's buy an adult ticket for seven bucks, and two kids under 14 can get in free with you. Or maybe it's a ticket, hot dog, soda and chips all for $10. The point is, bargains are there to be had. "Sure," you scoff — you old scoffer, you — "But the seats are probably in the last row near the roof and in fair territory." To a degree, true, but not completely. And the fact remains that Minute Maid is about as easy as it gets when it comes to the time-honored tradition of "improving" your seat. There's the Home Run Alley standing room, of course; there's also typically a wide selection of field-level seats sitting empty. Wait a couple of innings and then look like you belong.
