I worked at the Three Guys Marine & Motor Sales Company in Columbus, Indiana the summers of 1968 and 1969; I was 17. 3 Guys sold Glaspar and Steury boats, Mercury outboards and Honda and BSA motorcycles. Besides installing trailer hitches, and sweeping the parking lot, it was my job to uncrate the bikes and set them up.
It was like working in a Candy Shop.. ...
The biggest bike Honda built at the time was the CB450... aka, The Black Bomber (try to buy one of these today...)
