" Locking it just keeps honest people honest. A thief will get something if they really want it."
While I understand the sentiment behind that statement, I have to disagree.
Truly HONEST people don't steal things, whether they are locked or not.
THIEVES, on the other hand, may be deterred by a lock, or may merely be slowed down by it.
I wonder if vandalism and theft are REALLY prevalent enough to justify the worry? Yes, it DOES happen (apparently; I have no personal experience with either occurrence, except for the theft of a CB radio and a handy-man jack many years ago. But, that was in my back yard, not when traveling!) How many of you have had NO such occurrences while traveling around the country, and don't lock everything?
