this is a fail on so many levels.
first off their are better rivers to play with jet boats in the lower mainland. upper pit, lillooet, squamish, fraser, harrison, indian to name a few. the fact that the chilliwack river has not been closed to jet boats pass hwy 1 bridge is really odd and thats coming from someone who owned a similar boat in that video. way to much recreational users on this watershed for people flying up and down at 30 mph. just a matter of time before someone gets killed.
secondly, if its true that the individual through rocks which was most likely the case based off what the boat owners reactions were, he deserved the beating. at no point is vandalising someones property a good idea. would i have gone back to lay the smack down on him, probably not but i know some people certainly will. play stupid games, win stupid prizes. at this current time their are no rules saying the jet boat cant be there which as i stated earlier is goofy but legal at this point.
