i recently had my car in a small car show and i was concerned about the address part as i'm sure some envious types may consider coming by and having my 45 put into action. but seriously has anyone had any problems with car shows or afterwards and is this the norm for them to ask for this info and put it on a piece of paper and display it on the dash? just wanted to know, i left the address blank but was just concerned and didn't want any issues with theft or vandals.
