You need to move to a condo with a nice, secure, underused bike room. There's a Peugeot in our room that hasn't moved in 8 years and is not locked. I think I've narrowed it down to the ex-resident who moved out 5 years ago, as the frame is too tall to accomodate anyone else. The other benefit of a nice, secure bike room is that nobody knows that about 50% of the bikes stored there belong to just two owners. Me and my downstairs neighbor who also has tight lips;-)
