We skipped by climbing on the roof, teachers couldn't find us. We had plants in the greenhouse too.
I remember one year nearly the whole school was sick from 'paraquat', even some of the jocks & teachers.
Our art teacher smoked, we used to burn a 'doobie' in art class back by the kiln.
We had a lot of bonfires and river parties. A 'rural' school, most of us had our own homegrown crop.

I think HS gym class was probably a lot more dangerous when I was in school than it is today. I remember we had a climbing rope that went up about 20 feet with nothing but a thin Matt at the bottom in case you fell. And the peg board wall that you climbed up by putting pegs in the holes to pull yourself up.
Do they even have that kind of stuff in gym classes anymore?
