Anyone remember this? in These titles mean nothing.

It was great, wasn't it?

I think he might have been back from Vietnam and was restless. There was a lot of that at the time.
wiki says I'm wrong - not the first time - 'The series features Parks as the protagonist, James "Jim" Bronson, a newspaperman who becomes disillusioned after the suicide of his best friend Nick (Martin Sheen), and with "working for The Man" after a heated argument with his editor.

In order to renew his soul, Bronson becomes a vagabond searching for the meaning of life and seeking experiences that life has to offer (as revealed in the series pilot). During his travels, he shares his values with the people he meets along the way and to whom he lends a helping hand when possible. Bronson rides a Harley-Davidson Sportster motorcycle and, as such, he was viewed by some as a modern version of the solitary cowboy wandering the American west. The motorcycle had previously been sold to Nick by Bronson. After it is left at the scene of the suicide by his friend, Bronson buys it back from the widow.'

It might have been before your time. 1969/70. and it only ran one season. wki lists each episode and they really were interesting. https://en.wikipedia.org/wiki/Then_Came_Bronson
