The Technical Drawing teacher at my School (616) knew the code to the alarm, so snow days were a blessing for us. We'd go to the school about 10am and work all day.
The school building was really 3 buildings attached together though, (Middle School, Technical School, and High School) so once or twice we've walked a
little to far up the hallway and set off either the high school or middle school alarm. Those days were
fun.
