At my current assignment it's not practical to sign in and comment so I've been with you folks in spirit only.
I agree with the "public park" comparison for our lakes. It is perhaps the best way to get across the public domain concept. I will keep this in mind the next time somebody gets territorial about "their" slice of the lake. As a former frequent user of our public parks I have to say though, there are a lot of "Ranger Boneheads" on the trails so don't expect too many B/H's to see the light.
