Visiting an airport can be a stressful endeavor, so it's always nice to have a few distractions. There's a rather fabulous one at the San Francisco International Airport (SFO), currently, and it comes in the form of historic maps. Culled from the David Rumsey Map Collection, this in situ exhibit contains dozens of maps that document the city's development. On this site, visitors can view maps of proposed freeways across the city from the late 1940s as well as early maps of the Spanish colonization of the Yerba Buena peninsula. All told, the site has 12 images and visitors can continue on to the David Rumsey Map website to see each map in greater detail.
