Weather and conditions can indeed change instantly. I saw some very irresponsible boating on the 4th of july weekend. I think it should be mandatory that everyone operating a boat have taken a safety course with a certificate to prove it. I know this might be impractival with the rowboat renters. Some of them take the biggest risks. When I see children without life vests I think they don't know how close they could be to a mortal tragedy. Every year someone dies because they didn't have their life vest on. I know the coast guard can only do so much. Everyone gripes about being boarded. However it is a lot less painful to pay a find for negligent behavior than to have to explain that their child is dead because of an error that was forseeable. Let's be careful out there folks.
