My club (or, mostly AirborneVespa) is setting up a new cannonball to be run next June. Close to 1000 miles in 2 days. No chase trucks. No GPS systems. One class (vintage/shift scooters). No point systems - best time wins. I'll most likely be doing it on my 90ss, as the more uncomfortable you are, the faster you should go. It will be based around the DC area.
edit - and as it isn't a true cannonball, the name should be changing.
