I will leave it in a commuter lot. I have put it in paid parking at a city parking garage, I have left it in a state park (let the ranger know when I planned to be back). Left them at a bike shop in a shopping center. Church parking lots with permission. Fire department parking lots, with permission. Airport parking lots, train station parking lots, etc. I have also spent the first night at a local hotel and left the car there and spent the last night there too.
