I've mostly ridden 50 shifties but done it on mopeds, a bunch of us have. it rules. it's some of the best riding anywhere in perfect time of the year (well - except leaves on the turns) but it's an incredibly awesome ride. Suffering with Raniel is also HIGHLY reccommended as is camping at TWO and getting stupid with swoops the night before and maybe even the night after (tho be aware, you may be pretty wiped)
Suches were some of the best days of my life.
