It's a shame things are not like they used to be....everything changes though I guess. Personally, I think the permission slips should be made mandatory. In my area of IL trespass is a major issue. I know I am quite tired of having my stands, cameras, blinds, ect stolen off my private property with clearly marked property lines. I am 100% sure it is by fellow hunters who mistakenly think they have free range! I get the signed permission slips when I hunt elsewherejust so there is no question.
