I've been riding motorcycles for many years, drove school buses, concrete trucks, over the road 18 wheelers.
spent 20 years working in hospitals in radiology and the OR.
Been hit 3 times on the bike, rear ended on the bus. cut off several times in the trucks, and had to deal with Dr's with NO common sense.
take those same people, put them in a boat,,,,, and there you have it.
1st rule of motorcycling, EVERBODY is out to kill you! guess it applies to boating too.
