There you go. I see all these signature lines with thousands of dollars worth of saws and it looks like an invitation to come and steal them. It isn't hard to track down a person who posts public forum on the Internet.
I keep my stuff locked up and I try to avoid advertising to strangers what I have locked up. I'm especially leery about Craigslist transactions and do my best to have whatever item is for sale out in the driveway with everything closed up. I am always surprised when I buy something from Craigslist and people invite me into their garage or even their home.
That person you just met may be the nicest person in the world but you don't know who they know. The conversation at the bar later may go something like: I was just at this guys house and you wouldn't believe he had XYZ and ABC in his shed out back. He didn't have a dog or a security system or anything and he was telling me how he is out of town for work all the time.
Bottom line, if somebody wants what you have bad enough, they will take it. There is precious little you can do to stop it and IMO you would be foolish to put lives in danger to protect stuff. OTOH openly advertising what you own to strangers probably isn't a good idea either.
I try to keep my front yard and house in as poor condition as I can. Piles of junk and cars up on blocks. I keep telling my wife it is the best security system money can't buy.
