For some reason I've also never been on the Columbia, just the Mark Twain.I never got to aboard on the Columbia or Mark Twain. I would love to try someday.
But I have NO desires to do the canoes. I found myself extremely tired to paddle the river! I can't do Autopia or the submarine either. Autopia is insanely slow and gotten me lower back pain. I had countless of terrible experience of smelling people bad body odor in the submarine. Never again!
