I just sold a home in the Lower Highlands in Boise, Idaho that has a detached man cave, similar to one of the photos in this article from houzz.com. Funny thing is, a man cave is indeed important to any couple. After all, us ladies love the pampering at day spa, so why wouldn’t our guys like the pampering of their own space? And, for me locally, that means their own private Idaho. Insert Smirk here.
