CenCalCruiser, What kind of boat and are you taking it ?
Bass lake is one of the nicest lakes around, but if you have a loud/fast boat forget about it !! Not to mention you will need to buy a Bass lake permit (price based on HP). You have to launch and immediately go to the Sheriff island for inspection and to get the permit (good for one season).
Millerton is ugly and full of idiots !! But bigger.
My recommendation would be Shaver lake. Nice lake, nice scenery, nice places to camp. Get a hold of Mark (Sanger Pete). He has a cabin up there (Shaver) and can give you the best info.
