The Steep Hills of San Francisco

San Francisco is built on some really steep hills, which led to the development of the cable car system. The streets are also steep (especially with the imposition of a grid system) with the most famous being Lombard Street, built in a zig zag fashion to enable cars to travel down safely. But there are a few others, which are almost as steep, where cars have to park perpendicularly and the pavements have steps.
