This is the probable route of the 1915 Electric Sociability Run adapted for current roads. This route was determined from researching the descriptions given in several contemporaneous newspaper accounts. The 1915 Sociability Run for electric car owners began at the Connecticut Ave. entrance to the National Zoo at 4:00 PM on Wednesday, May 26, 1915. The 12.5 mile drive ended at what is now called Hains Point at the southern tip of East Potomac Park where a luncheon was served. Interactive map.
