When and What:  1920's? Water Street Excelsior, Minnesota. Notice the trolley tracks in the dirt street. Excelsior was the main terminus for traffic from Minneapolis to towns around "the Minnetonka" as many people called it. (Minnetonka means "great waters") Hey, I like that old barber pole with the red and blue stripe. They all used to have those to symbolize blood vessels because originally barbers were "blood letters". Also notice that modern street lighting in small towns could consist of nothing more than one incandescent light bulb in the middle of the intersection ... if there was any at all.
