The rock part no but the 500k paid for taxpayer tractor and disc, he could be right. Check out farm.ewg.org, it'll make your head spin.
Nobody likes getting jacked, It's important to make sure you are sure you know where you are when it happens. I got jacked once too, I was sitting on my land and some clown came walking from some joining land he claimed he had permission to hunt (Later confirmed) and didn't even notice me then sat down about 200 yards away. I waited for a while and he noticed me then shouldered his rifle and aimed at me or "just looked at me with his scope " as he put it, same difference to me. I waved my hat in the air and he came walking and asked me what I was doing there and how I got there, I played along with his game till he finally decided he probably should quit asking questions Then he answered a few of mine. Back in the day I would have unloaded his gun and threw it as far as I could but I nicely chewed his ass and he left way faster than he came. I've had deer shot and left, farm raised game birds ground balled and left to rot and barn cats shot all within 200 yards of my house, It Pisses a guy off and I'm sure many if not most other landowners have been through a few rodeos like this in the past too. My point again in case some missed it is be sure you know where you are and what the laws are before you smart off to a land owner or you are doing your fellow hunters more harm than good. If they are out of line and you know it then let them have it , No harm done.
Shoulda spun up some rocks on his prolly 500+k taxpayer paid for rig on your way out....
I thought it was a good idea and would have been funny as hell.
