Take that to heart.I had amateur radio plates... I got rid of them when a piece of hamsexy scuzz started chatting me up in the hardware store. He made some offhand comment about knowing which house was mine and that was enough for me. I had a wife and small daughter that were home all the time by themselves at the time.
Seriously, there's a lot to be said about *NOT* putting travel plans or status online in a publicly accessible location. Friends & family only, maybe, and make blasted sure your friends are trustworthy.
