We didn't stay in one spot snapping pics long enough. And were on public property the whole time. We were right across from the NG guard shack
though with the shelter pic there.
It's kind of a grey area. They might come over and ask what we're doing, but they can't really do much about it, as there was nothing saying we
couldn't park there, and we never entered their property. They could call the local police, and have them ask us to move, but that would be about
it.
