My wife and I will be there Saturday. Just look for the matching Marakesch Red K75Ss in the parking lot.
Northern California BMW Dealers will have a display in the middle of Expo Hall between Honda and Buell.
BMW MOA will have a booth as well as the BMW Club of Northern California. So while you won't get the full BMW Motorrad experience, there should be enough to keep you entertained.
Don't forget, your going to be spending alot of time at Gerbing, Garmin, Tourtech, etc, etc.
Have fun. See Ya there.
