Just returned from Mammoth..Nancy and I rode Friday and Saturday. The snow was GREAT and the weather was OUTSTANDING! (Sunny both days with about two to three inches of fresh snow between Fri night and Sat morning.
Met some locals who we assisted getting them un-stuck and rode with for the rest of the day.
We mainly rode the east side of the CA/395 which we were told by the locals was not very common to have such great conditions on the east side.
