+1. I've left stuff out there a dozen times and have gone back to get it and it's still sitting there or have received a phone call because my name and # is on just about everything.
Yep. I know if I see something left I will leave it unless I know who it belongs to. If I know, I will pick it up and try to contact them. It is the right thing to do.
It has not happened yet but if I ever ran across a firearm I would pick that up and contact Jack about it. Guns cost to much to risk.
I also think having your name and number on your stuff is a great idea. It will help get it back to you.
I do know if you leave a towel out there it is not safe. A couple of times I have seen one of the local dogs running around with a towel in it's mouth.
