It's been a long, long time since baseball was a cheap date, as Astros fans can tell you. Even before you start spending crazy money on food and beer at a game, buying a pair of seats hugging the foul pole will set you back almost $75. But there are ways around the madness -- very cheap ways, in fact. One of the cheapest is Coca-Cola Double Play Tuesday. It involves drinking a 32-ounce Powerade, but greatness requires sacrifice. Take the neck ring from the bottle to the box office, and you'll get two outfield deck seats for a buck each. Sure, the seats are in the upper reaches of the stadium, but here's the thing: Minute Maid Park is exceptionally open to improving your vantage point. If you prefer to be legal, get there early and take a standing-room spot by the Crawford Boxes. If you're more daring, wait three innings and move on down to field level. Then look natural, find an empty seat, and no one will stop you. As for eating and drinking cheaply during the game, you're on your own.
