Thanks to years of litigation and perhaps some genuine concern for the kids' safety, school basketball courts around the country are routinely ringed in padding. Not so in this subterranean basketball court, located beneath a 10,300-square-foot Tudor Revival mansion in Clayton, Mo. Nope, here the padding has been replaced with a stout brick fireplace. While it seems inadequately sized to heat the cavernous space, it sure is well positioned to crack someone's head open. For all you risk-takers out there, this suburban St. Louis accident waiting to happen is listed for $2.55M.
