First off I feel bad for the family,s of those lost in that accident and the statement that it takes a tradgedy to slow people down,I wish that were true the deaths have only started with big power boats and PWC,s .I went to a F.B.I. scvhool on physicological profiling and are test subjects were snowmobile,P.W.C.s and dirt bikes,ATV,s and motors cycles, Now mind you this is not a science and only goes by probabilities and not all are like this but MOST ARE. The typical person that partakes in these activities are of below averege intelligence,are adreniline driven, can,t stand fishing or canoeing(not fast paced enough) are proned to drink to much(how many PWC,s do you see by the shoreline taverns and snowmobile during snow. Drinking is part of the profile,it is part of the game. Party people type thinking. the personality trait is anti authority. thats why they like it, no rules and the rules there are ,almost impossible to inforce,not enough cop,s most of them have been trouble makers all their lives and most are self serving , they could care less about you or any thing else, they could not stand and watch a perfectly calm piece of water without driving a PWC and messing it up or a snow landscape with out a foot print the would get a snowmobile and mess it up. they are not able to just sit and watch nature and enjoy peace & quiet ,I realy feel sorry for them. The only reason they are not banded from using them(PWC,s) is MONEY.there are enough deaths on the books to show they are deadly(they make everyone wear seat belts yet they still allow those killers on the water,80% of all water deaths in boat accidents are PWC,s but thats why they do it. IT,s RISKY.
