Agree 100%. Too many trespasser claim ignorance.....just like politicians.
I would think that 99.9% of the land east of the Mississippi is owned by someone.
Assume no one allows you to trespass.
Always ask.
I also let my neighbors know when I am working near the boundaries. Lots of folks target practice around here, and I’d rather not get shot accidently (or on purpose, for that matter!).
