Wow, some of y'all like pole vaulting over mouse droppings...

So, how does one determine, on public land, what is "open to the public" and what is "closed to the public"? I know laws don't always follow common sense, but using logic only, I would think that for something that is owned by the city/government, it would need some type of indication that it is closed to the public in order for it to be closed to the public. If it's open to the public, then he should be able to fish. If it is closed to the public, it should be indicated in some way.

I understand the laws are different for privately owned land.
