Things have been going that way in my area pretty rapidly over the last 5 years or so. I used to have permission to hunt over a dozen properties and now have permission to hunt about 4 (and I am paying to hunt one of them). Most of the landowners who no longer allow me to hunt on their land stated that slob hunters are one of the main reasons for their decision.
They're not making anymore land and if I ever find myself in the position to buy a chunk, I fully intend to do so.
It's looking like it's going to be a hot one on Saturday, but I will be there regardless of the weather. I saw a couple of good bucks last Saturday evening in the fields, so I haven't lost hope yet.
Good luck all
