Anyone have an experience with this in NYC? I returned to my locked up bike, and found another lock on it! It was a huge padlock around my chain and bike frame. Extremely snug. However, I was able to unlock my locks and walk the bike home. I had to buy an angle grinder w/ a metal cutting blade ($50) to get the lock off.
I've read that people steal bikes this way, only they normally attach the lock to something immovable to prevent people from doing what I did. Anyone with a similar experience? I've been locking my bike there for a while now, but am now afraid to do so. If this is a common prank or something people do when they're pissed off at cyclists - that would be one thing. I'd like to know before I lock up there again.
