A full-on bike stand in the garage would rule!
The place is a mess. We've got five bikes in there, six if my flatmate's girlfriend rides hers over. Usually my bike is locked to the gas inlet, my flatmate's good bike is locked to the sewage outlet (gf locks hers to his), his beater bike is locked to itself and leaned against one wall, as is my other flatmate's bike, plus there's some random bike (former resident's?) unlocked and leaning against the other wall on top of a random bunch of crap. Just as well none of us have a car - there's not room for anything more in there! Actually, there wouldn't be room for more than a little hatchback even if we cleared it out completely. Noone in our street actually uses their garage for their car.
