I usually watch from home. I have a pretty nice setup for watching games so I often have friends or my dad come over to watch with me. One reason I like watch from home is so I can smoke green while I watch the game with no worries.
Watch from home and big games go over a friends. All I need at home is HDTV, chips, beer and hoagie. I'm happy. I'll have the net up so I can check scores to other games. Now with my iPhone I have an app for that so this will be a first for me. The only time I watch games online is if the local matchups are crappy. I usually dont like the 4:15 games on ABC. The color, commentators and sometimes matchups suck. Oakland vs Jaguars. Weak!
I've never been a sportsfan who listened to the radio. In fact I dont think I ever listened to a full game on the radio. I've listened to parts of it because someone else had it on.
