your property or not, if you do that you suckI own 10 acres in OC NY which I built a home on 4 years ago. I pay $183 a week in taxes and expect to have my peace and quiet but the last couple of years the renegade riders have torn up my back hill. I used 2 1/4 in concrete cut nails sharped on my bench grinder. They are hardened steel. Nailed them into a 3/4 in lath which is screwed into a 2X4. I buried them on the trail so just the nails were above ground. The nails pull out of the board and stay in the tire. Seems to have worked, I also used fluted concrete nails with the same method. Both are hardened steel.
