so many of these replies are childish and dangerous, i ride bikes, and atv's i've stumbled across patches before, thats when you ride away nice and slow and dont look back and dont come back til the season is over out of respect. Fishing line is one thing, but piano wire is another, i've had friends severly hurt by green communists like that that go and read the green peace war book and decide to throw out nails and piano wire and some poor shlub is out havin some fun doesnt know hes near your patch and he gets decapitated by a piano wire set at head level.... worse is when your actually on OHV land where your allowed to ride and go out and have fun and theres people ILLEAGALLY going out on government land and setting traps for the exact people that the land is designated for their use. you really want that guy and have that on your consience over some stupid ass plants? I really dont think so. Put fishing line out like a screen all around your plants about 15-20 feet out go from the ground to about chest level worst that happens is some lacerations if your using real strong line no decapitations no loss of life or limb and you know if s1 has been in your shit. Then you just wait with a dog and a shotgun and find out who the fuck it is.
Nail punji sticks and holes of death are a very bad idea and its why so many of us that grow low key in the hills get into trouble is because of idiots like that rigging their grow area.
