What made you decide to do that? Cool... I kayaked once before at long beach, signed up for the Intro class. I don't think it was a Ken williams... who's that anyway? Anyway, kayakings okay, i'd say. I enjoyed river rafting much more, mostly because we were using 1 man kayaks and it's not much fun paddling alone. You'll spend most of the time learning the basics, turning the boat over, then you just row about 45 minutes till your back. Just remember to bring some change for the toll bridge towards long beach. Coming back i had no change and asked some lady for 1.25 to get across.
