Between 1916 and 1924, Henry Ford, Thomas Edison, Harvey Firestone, and John Burroughs, calling themselves the Vagabonds, embarked on a series of camping trips. This image, from 1921, shows the Vagabonds (minus Burroughs, who had died earlier in the year) dining with family and friends near Hagerstown, Maryland. One of their friends at the table is President Warren G. Harding.
