When your friends or co-workers question you why you put so much effort into anti-theft devices (The CLUB, starter kill, transfer case lock, etc.) on a 25 year old truck so it won't get "Stolen."
When every gardener in town asks you if you want to sell your truck so they can take it to Mexico.
When you get hand written notes placed under your windshield wipers every month or so of people asking if you are interested in selling your truck. (All true stories.)
