Oh gosh! Well found.
This particular man I am talking about, was a Ranger in 1921 (and before) - but in 1921 he was specific about his area ie, the places. There was about an 8 mile one way trip between these 2 places.
I can't imagine him just doing one backwards and forwards walk each day - but who knows!
That's why I thought he would sail up and down several times daily, but just don't know.
It's not really important, I was just curious. Thank you though for looking - much appreciated.
