short title clip
ran 1956-1957, so I was nine. Had horses, cavalry, lancer charges so my age cohort really liked it. We tied handkerchiefs and bandanas to the bamboo poles that came with rugs and charged around on our bikes for that time. Good thing there were no stray dogs in the neighborhood.
Oh, add Rin-Tin-Tin
