Yikes.. I think that may have killed me too.
Almost the same happened at my property.
I had found atv tracks all ov er the front of it, and finally they were rutting it up enough to make it hard to mow.. the hog was starting to scalp in some areas.
Police were as useless as wet noodles.. didn't even want to make a report out * ( they did.. only after I went to the top... ).
In any case.. i put up a t-post and barb wire fence, and pipe gate.
I put up reflectors on stakes along the new fence, Bright neon yellow flagging tape along the top line of the fence, and put up that red/white DOT reflector tape all over the gate. And posted signs out the yin-yang.
Was fine for a few weeks, then I had to go back and repair it. Someone plowed into it, took out 2 tposts.. didn't break the wire.
Found lots of red plastic atv parts.. I'm gonna guess it hurt quite a bit too, and that the alcohol quotent was probably pretty high as well.
I gues that proves the 'stupid hurts' saying true.
