That is a piece of brush. The lake is nearly 12 feet low right now, alot of stuff that is normally under water is exposed right now. I actually have caught alot of bass off the brush pile. I placed it there about two years ago, along with about 20 other half trees. They make great places to find fish when no one else can.
Yeah, the garage houses boats and large parts but sails and other soft stuff are in the room.
