Nested into a southwest slope of Mount Davidson in District 4 is Sherwood Forest. Never heard of it? That's because at justtwo by three streets it's San Francisco's smallest neighborhood.Smushed between St. Francis Wood and Miraloma ParkSherwood Forest starts at the cusp of Yerba Buena and Casitas avenues and covers all of Lansdale Avenue and Dalewood Way which faces the dense vegetation of Mount Davidson Park. In total there areabout 200 homesin the neighborhood. The only street that starts and ends in Sherwood Forest is Robinhood Drive a street that's so hidden and difficult to find that the lateSan Francisco Chroniclecolumnist Herb Caen once penned an article about getting lost trying to find it on his way to Thanksgiving dinner.
