I get what you're saying, but it would help if you were able to see the land itself, so here's a picture of the land in question. The grass and other plants are up to my elbows most of the time. The grass surrounding the stream is abut 1ft. The two and only two trails are all grass and not worn down in the least bit. The creek is intensely cold even on a 110 degree day there's no way you'll ever want to get in, and there's a steep embankment making it hard to get into. Crossing the creek, if I were to guess, happens about 2-3 times per year. The only attraction to this field is the stream, so there's really no reason to wonder around the surrounding field. I live in a considerably rural part of Wisconsin, so that plays into it (in my opinion).
Yeah, if you look at the picture there are clusters of tree's at least 25 years old.
From what I know, the people that travel this little creek either trout fish or walk the creek. I've lived here for 26 years and I've never crossed or had a reason to, even when trout fishing. That doesn't entirely mean someone else wouldn't have a reason to cross, but I'm holding out for ignorance and deception with a bushy plant. I was reading about some gorilla grows that got caught and made it on the news and they're all caught with a trail cam, then a warrant was issued to search their houses for curing cannabis. That's one of the reasons the field and lack of trees is so appealing. When I check the plants I'l be equipped with a fishing pole and a tackle box. Plants will be curing at someone else's house. They definitely don't have the resources around here to surveil 2 plants spread out in a field.
