I found this new public lands blog (from an attorney in WI) that I thought you might find interesting. It’s well done and he’s obviously pro-access. Good stuff and with links and references. It’s factual with plenty of back up data/links. Because he is an attorney, it does have just a bit of a legal slant/interpretation that is very helpful to understand some of the public land issues.
