I would much prefer to bring the bike inside and in one work place I am able to drag it right into my shared office. This is in a relatively high crime area and would not want to leave even my old commuter locked up outside. My other work place is in a more salubrious location and I leave my bike outside locked up to a fence and have never had a problem. One day I forgot my lock and a friendly staff member let me park it in an indoor storage room.
