I'm not proud of this, but I'll share it. My property I hunt is down in the Missouri River bottoms here in MO. I discovered ATV trails that weren't our own. They went all trough our fields that are bean fields. I also found a rope swing and camp fire area where they were partying. So I cut the tree down that had the rope swing and picked the trash up in the party camp fire area. Then I trailed the track to where they come into on the property. Found a little opening trail that they were using. I dug up a strip along that trail about 8 feet wide and just deep enough to bury a 2x4. In that 2x4 I drove nails through it and painted them brown. Buried the board and made a little road spike. Haven't had to much trouble with trespasser since. yeah it's a little overboard. But I don't own the property I hunt, it's my works. And county sheriffs department hasn't done crap. So I took over.
