That does look like fun. Totally different from a Harley run. Wouldn't mind doing that myself.
That Roswell is something else isn't it? I rode there from Phoenix, AZ and back on my Vino 125 a couple years ago. I have not been to Show Low, AZ on a scooter, my Vino won't climb the mountains, and it's a little farther than I would want to take the Stella without a rescue plan for when it broke down.
I won't spend more on a bike than I think it's worth, but if it's a good deal, I don't seem to have a problem buying bikes I don't need.
