A fellow RVer in his 60s told me he had completed, not all that long ago, the Iron Butt Association's "Lower 48 in 10 Days" motorcycle challenge. Here's a link
to the rules. Partway down the page is a link to sample routes.
As this fellow told me about what the challenge entailed, I had one of those mind-dislocations that occurs when I discover something almost totally foreign to my experience (and personality). Compared to that ride, Dr. Olsen's suggestions are like strolls in the park.
Perhaps I should join the "Slow RV" movement, if it exists. ;-)
