I remember seeing a post a few years back when I first started kayaking, something titled along the likes of 'The Art of Strappage.' It had a pic of Derk's ole' suby legacy I think with like 12 (or More??) kayaks strapped to it.
I think it would be a nice gesture to his enthusiasm, character, and to Him as a person to see some pics of people's shuttle vehicles Creatively Strapped full of kayaks from today.
I never had the pleasure to get to know him personally, but he shot me a private message once when I first started kayaking when I posted up asking for Beta on the BV town run and that boat chute/dam. Gave great beta, and even offered to run it with my group and show us down. We never got around to it, but based off of all his posts, he was a very helpful and knowledgeable guy to newbies just entering the whitewater realm.
