From a 1951 history of Seattle, entitled Skid Road.The mayor under discussion was a passionate orator, and nicknamed "Holy Ole" (yes, it rhymed).
[Mayor Ole] Hanson was working in Butte, Montana, in 1900 when he injured his spine; doctors doubted that he would ever walk again. But Ole's hero was Teddy Roosevelt, and Roosevelt had conquered illness by exercise. Hanson bought an old covered wagon and rigged up a combination harness and sling, which he fastened to the rear of the wagon; it enabled him to walk behind the prairie schooner. With his wife driving the wagon Hanson trudged along behind. He walked the seven hundred miles from Butte to Seattle and reached the Sound country physically fit.
