My senior year I was at the speedway every school day but four from the day it opened until race day. I was in a vocational program and would leave my regular HS at noon and rather than going to the other HS I'd go to the track. The vocational teacher knew and I still passed somehow.I dont know how old you are now but when I was in high school we probably would have been friends....lol
Sounds like my teenage snake pit days
