This sucks. I'm gonna miss the Cards-Braves game today while driving to Dallas to look for a new apartment, and I'm gonna miss Nats Game 1 while driving back. Rooting for a team since April 2005 only to miss its first-ever playoff game.
ESPN Radio carries all the games. If there's a sports radio station you can pick up, you might have a good shot of getting the games. Check here for a list of affilliates:
