I am a proud owner of a man cave. it has everything I need and then some.
Three TVs, two on cable so I can watch NASCAR and the local NFL/College games and one on DirecTV with the NFL season ticket. A large fridge full of beer, a chest and upright freezer, a pizza oven, large popcorn machine, 48 inch grill top and a full bar

also a Xbox and ipod dock station for those non football boring months I'm forced to deal with.
The thing is I'm NEVER alone in the cave. My wife spends every night with me and our 20 year old daughter and several of her friends are there 3-4 times a week. It's just a fun place to hang out.
Cave rules are simple.
Anything you bring in the cave must have something to do with the Minnesota Vikings or the Boise State Broncos. Beer of any kind is welcome. The remotes are mine
