Many years ago I grew gorilla style in a National Forrest in Wa state.
While looking for good places to plant I stumbled across another persons grow. They were real nice plants, well cared for. They were about a mile 1/2 from my spot.
I just made a mental note of it and went about my business. However I did return from time to time to see how they were doing!
One time I spotted a couple of large weeds growing under the plants. I pulled them up and deliberately left them on a stump where they were sure to find it! ( I have a twisted sense of humor)
A year later at a neighbors birthday party, while outside smoking weed with the tokers, I told that story.
One of the guy's in the 'smoking circle' ( I didn't even know the guy at the time) said "That was you!" "You SOB, you drove me crazy!" I laughed out loud! This was too funny!
I actually got to hear everything he went thru trying to deal with it. He said I was the only one to ever find his spot. When I told him I would return on occasion to check on them, his face turned white!
He was mad at me at first, but in the end we both agreed I left his garden in better shape than I found it!
