The problem is not staking off the finger dunes.. its what you USE to stake them off with...
I agree with what you say, and I can see this as a safety risk. I think just using cones would be great(no rebar) because I do feel that letting people know that my camp is on the other side of the finger is important. I have seen plenty of people jump a finger directly into someones camp. Isn't it the same problem as people going to fast on the flats and blowing by your camps?? I will absolutely only be putting cones on the fingers where we camp from now on i appreciate the info.
