Aww... I disagree to some degree. There are some nice roads out here... Larry seems to fall into the bucket of people who move to the West coast and never want to leave (I know a lot of people like that). I'll give you the other side if that's OK, someone who loves the East Coast and enjoyed my time in Cali but could never live there.
So, for East Coast riding...
Long Island has some great twisties, especially as you get further out East. I am waiting for my friend Tommy to join the forum, he will be able to give you more specifics on which roads (I am a group rider follower, so never know where I am).
Sussex county NJ also has some good riding. Again, my friend Jason will have to pipe in here. I'll shoot him an email to join up shortly.
While you're not going to find roads that are exactly like the Bay Area, I don't think it should completely discourage you from moving out here if that is your plan. You could also try racing Supermoto... we have some fun tracks out here for that.
