Maybe there could be a way to highlight land ownership. For example, we have some private properties on there that the public is not welcome to visit without permission. That would be good to make as clear as possible. Other sites are very accessible and we can encourage people to stop by those on their own time.

I especially like the landowner ideas, and the comment about whether it's a good site for visitation. Thanks for all this feedback!!
