Roy Rogers, 1958 magazine cover photo on a Harley, and an Indian in 1946

Roy Rogers rode out to Hollywood in the early 30’s on a motorcycle when times were bad and transportation costs were high. He took a liking to the sport, riding his Indian until World War II. Out of the saddle for 16 years his last bike was a 74 cubic inch Harley-Davidson.

and he didn't play favorites it seems, not only did he advertise for Harley and Indian, he also advertised for Honda and Nissan http://justacarguy.blogspot.com/2016/09/roy-rogers-after-end-of-his-cowboy.html

It's too bad he lived so long before me, I'd have liked to have met him. I bet he was one hell of a nice guy.

Thanks Steve!
