What? They have Oktoberfest in Tahoe? Sweeeet! I'll look into it. My last Fest was in Cotati (up near Petaluma). We stayed at the KOA, and rode our mountain bikes to the park many miles away. We came back after dark, hammered off my ass, and I wiped out on the side of the road. Good times!
I haven't ridden the Scorpions in the rain much, but they are supposedly designed for all weather/all roads. They come stock on the Ducati Multistrada as well as your bike. The only terrain they don't work on is mud and sand. My next set will be Continental TKC-80 tires, since I would like to get farther off road.
