We all made it down to I-80, went a couple of exits west to Yuba Pass, and proceeded to Kelly Lake, where lunch was served. Because of limited room for vehicles at the top of Cisco Butte, we went up in three groups. Someone in an earlier group got off the side of the road and probably due to deflating their tires too much, suffered two blowouts. I still don't know why it takes two towtrucks to fix two flat tires.
