I am not dismissing your signs at all! They are actually needed. I like the metal signs, but so do idiots around here. We went to plastic coated cardboard signs based on local law enforcement recommendations. They are dirt cheap if you buy them at the Sheriffs Office.
JKB....I am sure some of the locals may take a shot at my signs eventually. Sad isnt it? But such is life. I may take your advice and see if the Sheriffs here in Texas have anything like the signs you speak of. Heck it couldn't hurt.
It's also nice if you have at least one good neighbor you can trust. Of course that's not a given, but if you have at least one that likes to play "cop" and keep an eye on the place, maybe run people off while you're not there. My brother will probably be living out there 3-4 days a week in the next couple of years so that will help.
I had a friend tell me this morning that he bought some land for deer hunting several years ago and caught some guy hunting on it once and the trespasser got pissed off and told the land owner "
hell all you city slickers come out here and buy these places and think you own it when we've lived out here all our lives".
