As I said elsewhere, but it is worth repeating... If a game is re-aired (usually late at night or next midday), the NHL game repeats are NOT blacked out. NBA and MLB repeats are blacked out.

I would suggest a Roku or Boxee device. They're inexpensive, easy to install, and you can take it on your cross-country trip, ensuring you don't miss games. Try THAT with Center Ice!
