Real nice. That was a very nice song and depicted a way of timber life at one time.
I remember watching one of those "logging" movies back in the very early 50's and my dad warning me that you cannot swim with your clothes and shoes on. I grew up in the Southeastern US but it still gets wintertime down there.
All I remember about the log trucks in the late 40's - early 50's is that they were single trucks and usually had no doors and nothing on the back except cross beams front and rear to hold the logs. They used cross cut saws. First chainsaw I ever saw was a McCulloch two man and that was used by a trimming contractor for the electric power company in the very early 50's. As power saws became popular in the mid 50's, it was bow saw country.
My great uncles and grandfather were always in the hardwood sawmill business and they would snake the logs with mules to a landing ramp where they rolled the logs onto the trucks. I remember they got a D4 for bringing the logs to the ramps but soon sold it because of high maintenance problems.
My mother's brother always wanted to be in the trucking business when he was young in the late 40's and he had a Chevy with a single axle flat bed trailer. He hauled finished lumber. By 1952, he was into plumbing with my father.
Those pulpwood type log trucks that just hauled pine, would have pine sap built up on the steering wheel and gear shift. It would even be on the seat in chunks. The bow saws had sap all over them also.
Pulp wood is now done with harvesters and is full length out of the woods. They might get a couple boards out of a tree and then the rest is chipped to go to the paper or plywood mill. The old family land belongs to Georgia-Pacific.
