Bob, this is a subject I would work hard for. I'm all for sleds in the right place. But in pristine (no dam, free running) rivers like the Olypen, I'd be up for a law of no motors above a certain point in those rivers. For me (I know, I know, it's all about me!) there is nothing worse than taking a relative or friend for their first drift to introduce them to the beauty and peace of our rivers and having a sled come ripping around the corner straight at you at 20knots. It just spoils the whole vibe. Like Coho said "You could take your riding lawnmower into the grocery store" but why?
