I remember this show from watching the original broadcasts when I was pretty young, only I did not correctly remember the title. I recall the sub-theme that Hank could run so fast that the athletic coach wanted to know who he was, there was a certain implied irony (he was a natural athlete and could probably have attended college on a scholarship if he wasn't so preoccupied with auditing for free and running away). Long ago I tried to remember what the show was called and I confused the title with another show of the era so I probably doubly confused folks when I was reminiscing.
Anyhow, the show made a positive impression on me and I too had the problem of no one else having seen or remembered it until I did a Google search and stumbled upon it here.
