Mamie Johnson remembers mid-fifties life on the road for the Indianapolis Clowns of the Negro leagues, in Michelle Y. Green’s first-person biography, A Strong Right Arm: The Story of Mamie “Peanut” Johnson:

Sometimes that raggedy old bus would break down and we’d wear our muscles out before the game pushing it uphill. And we never knew if we had enough gas to make it from place to place, ’cause some of the towns we stopped in had “Whites-Only” gas pumps. That never made sense to me. Seems like if folks were so anxious to get rid of colored folks, they’d want to give us the gas we needed to get on down the road. (p. 86)
