ManCaves for sports fanatics

We’ve been posting a lot about the vehicle aspect of ManCaves, but there is so much more you can do.  This link has a bunch of photos with some really cool and creative ManCaves that let a sports fanatic live out their dreams.  In talking with some of our current reservation holders there a few folks considering some ideas like these, and we certainly hope they build them out and then invite us over!  What ideas do you have to upgrade your  ManCaves unit?
