#31 San Francisco 1October 15 in the United States
We rented bikes to explore the city, essentially the Golden Gate Bridge!
As you know SF has a lots of ups and downs, so we walked to the Fishermans Wharf where we got our bikes. From there it is an easy 10miles ride over the bridge an back.
We also passed Lombard Street, Palace of Fine Arts and cruised around Presidio.
