Nice start on the man cave.
I am about 3/4 the way through my basement remodel. I kept a 21'x32' room for the man cave. I hear yea about the water issues.
I removed my gutters about 3 years ago due to roof damage, ice damns. When I replaced the roof I never put gutters back on. With the 3' overhangs all the way around hte house the only time my basement shows any water is once or twice a year, couple little puddles. In about 3 weeks I'll be installing a French Drainage system. I'll put it about 2' down right under the overhangs. That should take care of any water problems.
Guess I'll have to start a thread of my own. At least my man cave wont take 2 years.
Just kidding man.
