Opportunity is missed by most people because it is dressed in overalls and looks like work. - Thomas Edison
As long as socialist run government, what's yours is now theirs too.
It's a matter of respect for property, and in today's litigious society, sometimes a matter of liability. I doubt Johnny sits on his porch with a shotgun challenging everyone who walks up his drive, but what happens when one of his goats bites a kid in the ass as they cut through his land, or the kid on the 4-wheeler breaks his neck when he runs into a tree Johnny carelessly left standing?
and its even a bigger shame that people are so uptight about people being on their land.
