I remember that the drafting teacher was a really nice guy, but I can't remember his name. The electrical shop teacher, who was also one of the football coaches was also a lot of fun. I didn't really know the woodshop teacher, but he's still an active member of the AAW and does some turning in his retirement.
I had plenty of memorable teachers, all of which were influential. I would say that the one that had the most impact was the music teacher who was a wonderful person. She died from a second bout of cancer many years ago unfortunately.
