It's the hottest day of the trip and, in parts of the Midwest, of the year with the temperature hitting 100 and the "feels like" at 110. it's the kind of heat that the AC in the trailer can't keep up with and everyone his hot and crabby. We're in a beautiful campsite but who can enjoy it in this heat. Plus, Dan invents a new shower game called the "ice box challenge" so what could go wrong.
