Me too.

I've always thought about following the Lewis and Clark trail, kayaking the length of the Missouri, and biking over the rockies to get to the Columbia. I know that the Swedish mountaineer, Renata Chlumska, did a complete circumnavigation of the continental United States with a bicycle/kayak setup. She kayaked the coastlines and biked the borders with Mexico and Canada. But she used a rigid, full size, sea kayak. She towed the kayak in a trailer behind her bicycle, but I'm not sure how she carried the bicycle when she was on the water.
