What makes a room a "man room"? We read an article once about a study that found men's favorite room to be the basement (too dark and unappealing for potential female intruders), and women's the bathroom (often the only room in the house with a lock).
This article from the Seattle Times exposes the "man room" of one Dan Dolan, in a house he shares with his wife and two boys. What he created was a place to display memorabilia from his long-time hobby, deep sea fishing. Given free reign over a basement room, he chose antler chandeliers, a river rock fireplace, and faux-finished walls.
