You didn't say what part of California you're visiting, Northern or Southern, but if you're in LA drive Pacific Coast Highway, CA-1 from Santa Monica (a great place for food, fun shopping and their pier, north to Malibu, another great pier that just re-opened, Paradise Cove with Gidget friendly beaches and seaside dining and on north to Camarillo and Highway 101 with outlet shopping. Then take 101 back south to LA and see how the smart does on a long uphill grade. My avatar is from PCH in Malibu with my smartie.
