Who uses physical bike locks?

[j3gq_imp]

My excuses for never buying or using a separate lock ? if it was light it's useless, and a heavy one I don't like to carry around, or have it dangling from the luggage rack. Where on earth can anybody stash away a heavy, tough, serious locking lock which really secures the bike. What I do "carry" is insurance against vandalism (much cheaper than all-risk).

You gotta be careful with that. Some places in the US have these insane "booby trap" laws where a criminal can press charges against you for setting traps intended to be triggered by attempted theft or trespassing.

Are you serious ? Can you elaborate a little ?
