You're in California! That's just great! They have REI's!
Checkout the Marin Muirwoods 29er. They should also have the 26er, which costs about $100 less.
The Muirwoods has a wide tire width. It can be quite versatile. IMHO, it's an urban commuter, a mtb, and a credit card touring bike, all rolled into one. It's perfect for gravel!
Good Luck!
