Ah.

In that case, I just do as the locals are doing. If everything is attached to a bike rack and nothing else, I find a bike rack. People hate bike racks, so if they are in exclusive use, I have a good idea that there is a reason. If they are parked all over the place, I just find a convenient space where damage is unlikely to occur. I do the same with my locks: if everything is chained up with flimsy cable locks, I have no issue following suit, if both wheels are locked to frames with U-locks and the frame secured with a hardened chain, I'm looking for a bike shop to buy a better lock.
