Potrero Hill is a residential neighborhood in
San Francisco,
California. It is known for its views of the San Francisco Bay and city skyline, its close proximity to many destination spots, its sunny weather, and for having two freeways and a
Caltrain station.
Vermont Street is a north-south street in the Potrero Hill district of San Francisco, one of a series of streets in the Potrero Hill district named after American battleships. Between 20th and
22nd Street, near McKinley Square, the street has seven sharp
turns. This has led the street to be dubbed the crookedest in the world in competition with the better-known
Lombard Street (Vermont, while steeper than Lombard, has fewer turns). In an episode of
Fact or Fiction on the
Travel Channel, Jayms Ramirez measured the
sinuosity of Lombard and Vermont streets and found that Vermont is indeed more crooked (with a sinuosity of 1.56 versus 1.2 for Lombard Street). Sinuosity, sinuosity index, or sinuosity coefficient of a
continuously differentiable curve having at least one
inflection point is the
ratio of the
curvilinear length (along the curve) and the
Euclidean distance (
straight line) between the end points of the curve. This
dimensionless quantity can also be rephrased as the “actual path length” divided by the “shortest path length” of a curve. The value ranges from 1 (case of straight line) to infinity (case of a closed loop, where the shortest path length is zero) or for an infinitely-long actual path. Vermont Street is featured in a
chase scene in the
Clint Eastwood movie
Magnum Force (1973). Clinton “Clint” Eastwood Jr. (born May 31, 1930) is an American actor, film director, producer, musician, and political figure. He rose to international fame with his role as the
