I'm not sure I actually want a t-shirt: the problem with ballpark giveaways is that you have to carry them around for the rest of the game, and that seems especially painful if it's going to be a doubleheader.
Shirt or no shirt, I will definitely be at Nats Park today. I am considering whether I want to shell out $85 for the PNC Club, or whether I want to spend $12 on cheap outfield seats and hopefully sneak into a better section as the games go on. (I have an unexpired student ID so I get 50% off).
