Glad to see there's a whole site for ballpark enthusiasts! My friends are going to travel, by car only, to all 30 ballparks in 30 days, and make a documentary about the whole thing. They leave in mid April, and the first game they are going to is at the new Citi Field. Much of the money they raise from the DVD will go to The Boys and Girls Club of American.
