Check your local laws or store for Purple Posting Paint. I'd venture to guess most states have adopted the purple paint as a "No Trespassing" warning. The purple paint has some fairly specific requirements, like painting trees or fence posts every 100' and certain distances off the ground...
I would also not allow some game warden or deputy try claiming a sign is needed at all. A person knows if they are not on their own property, and don't have permission, they are trespassing....no signage needed!
There are specifics to how signs are to be placed too.
Yes, a person knows that they are not on their own property. But many times, a trespasser will say that they have permission to be on the neighbors property, and there was no way to tell where the line was. I say fuey, they should have been clearly informed/asked as to the property line before trudging around. However, to be fair signs are good ( and I think needed here, for court cases). Then I don't feel bad in any way about going to the full extent of the law.
