San Francisco Landmark - Cable Car - Milk Chocolate At the turn of the 20th century, there were 600 cable cars running on eight lines and 110 miles of track throughout the city. Despite extensive damage inflicted by the 1906 earthquake, cable cars still clang their way up and down hills, the last permanently operating manually-operated cable car system in the world, depositing delighted visitors and savvy locals alike to their San Francisco destinations. The tin holds 3 oz. of our Gourmet Milk Chocolate. Sold in convenient cardboard display cases containing 8 tins.
