Do they ban fish from the lake? If they're worried about human urine perhaps they should be worried about fish "by products".
After 9-11, when my fishing partner and I got thrown out, and almost shot by the Sultan Police, I have not been back. Last I heard is that the road was in trouble from weather, but that was posted some time ago. Beautiful lake to fish. Nice fish. What is not to like?
Please don't pee in the lake.
