I was lucky to find a bike rack on the first floor of an underground garage just down the street from my office. So it is out of the weather and doesn't seem to be disturbed. The only problem is that as gas gets more expensive and the weather gets better the rack fills up completely if you arrive late. I'm just beginning to explore possible storage options in the garage of our building. There are at least 3 bike commuters in the building (and its a small building) so it would have beneficial effects for a decent percentage of people.
