Tunitas Creek to the coast and back from Palo Alto through the old growth. Ride over the GG Bridge. Take BART to the east bay and climb Mt. Diablo and check out the 100 miles of view. Ride out to Ocean Beach and have coffee at the Cliff House or Beach Chalet with the lady. Take the lady out to Bodega Bay. Go to Olema and see where the earth shifted 20 feet in 1906.
It's a long list.
