My wife works every Saturday until 4:00ish, so I routinely have to DVR and watch the game late. It's not too bad, especially since we can skip through the commercials and such. The worst part is that I have to stay away from the TV until wifey gets home and let my friends and family know to not text me score updates during the game.
Curious - are you trying to NOT know the outcome of the game before you watch it? I mean, if you knew beforehand that we lost, you probably wouldn't bother watching it, so I assume you will try to stay in the dark. That could be tough at the parade since I assume lots of folks will already know the outcome of the game.
