in oklahoma, i mow a large piece of property. some **** keeps doing burnouts on the public easement around the property. is it legal to drive metal stakes into the ground to keep vehicles from driving on this side of the road? police said utility workers would just remove anything on the easement to work. people in the neighborhood next to the property are freaking out, had a guy pull a gun on me today. i just want to keep people from destroying the lawn i maintain and my family owns. any advise?
