Nope, I don't kayak, my step brother is a big river kayaker. He's been working on trying to get a kayak park built on the Mississippi river in the area around the Stone Arch Bridge. He goes up North for kayaking up there, I don't have any particulars, and he's kayaked in Guatemala.
I have a cousin who lives in Steam Boat, works a ski rental during the winter and guides white water rafting in the summer. I have yet to experience that either.
