The bear that tours our neighborhood opens car doors. If the car is locked he'll damage the handle, but if the car doesn't have food in it he won't damage the interior, so we leave our cars unlocked and make sure they're clean. I don't have a garage, otherwise I'd use that.

A couple years ago he broke into a neighbor's RV and tore the kitchen to pieces. IIRC the RV was totalled.

They also go through open windows. Saw an interior get totaled all because some m&m's were left on the dash.
