The Idiot Factor I refer to is a non-scientific measurement which operates in direct proportion to the number of Personal Water Craft. The more PWC's - the more idiots. However there is an "escalator clause" which increases the ratio close to 1:1 as relates to rental operations. Apparently anyone with a credit card can rent a PWC on Halifax harbour and are thus entitled to risk their own and other's lives with impunity.
Hardly a day goes by tat I don't see someone taking an unnecessary chance with one of these craft. Today took the cake however as HMCS Montreal had to warn off several of these pests with whistle signals - not once, not twice, but three times.
