Just chased down snowmobilers

This made me think of the song from the 60s (or maybe the early 70s), "Signs, signs, everywhere there's signs." Can't remember who the artist was. But there was a line in the song that went something like, 'I saw a sign that said 'keep out, trespassers shot on sight'. So I jumped the fence and said "Hey man what gives you the right?" Or words to that effect.

I know it's just a song, but there are people out there who believe property owners should not have the right to control their own property.
