I don't think it really matters where they are, as long as they are near the place that you do maintenance and prep them for rides. If I had a heated garage, that is definitely where they would go, along with all my bike tools. Set up a nice work area. That's where it's at IMO.

But this is all beside the point. They belong wherever the hell she says they do. The main point here is that she is not telling you to get rid of any.... THAT is a dealbreaker.
