Totally agree in every sense, but I think its WAYYYYYY more dangerous when people do it in a foreign place too.
We get people coming into cedar point at all hours, same deal with Put-in-Bay and a lot of them don't live around here. When I was a young I used to beg my dad to let us anchor out in the lake on the boat and spend the night. He refused even with all the lights on in the salon because he never trusted other boaters not to hit him.
as my uncle used to tell me "you could fill the whole f-ing universe will all the stuff you DONT know"
Of course maybe the greatest danger is in places you do know and you are overconfident.
