You say Evil Knievel and somebody else has related it to Elvis. This will be my 3rd rig and even though it has been a while I did get out last Winter on my brother's rig and it all came rolling back into my brain. Still I'm planning on taking my time getting back and if I have to stop overnight I will. 4 days and a wake-up!
I bought that exact Wing and sidecar in San Diego and rode it back to Salida, Co in '99 in mid November. What a trip! I kept it for a few years and then sold it to a retired teacher in Denver. Saw it for sale on Craigslist less than a year later. Hope you're enjoying it as much as I and my dog did.
