When I was a kid, growing up in central BC, Canada, the song I would hear every morning while eating breakfast was, the jingle,
"Yer in luck when you got a McCulloch chainsaw,
You got power by the hour in your hands,
With McCulloch, you're the master,
'Cus you keep a cuttin' faster,
Yer in luck when you got a McCulloch chainsaw."
The first logging camp I worked in (1957), used Macs, but my job was as a canter in the mill and part_time truck driver, so I didn't know the model number, or if they were all the same model . We were in some good sized first cut wood, so all the saws were equipped with a 36 inch bar.
It wasn't all good days, however, I can still remember one day, when one of the most experienced fallers was screaming at his saw, (like in a bad relationship) because it wouldn't start. I still chuckle when I think of it, because he was such a good mannered guy most of the time.
