When I was a kid school started at 9:00 Am, lunch 12 to 1 and class til 4:00pm. Consolidated schools changed everything and made everything worse. Ross Perot Told us the only reason for a high school with 5000 students is you have a better chance of a championship starting lineup.
My recollection is that school started at about 8:15 or 8:30. I was on a 70-minute bus ride in the evening with 10 in the morning. The kids who got on the bus first in the morning really had to get up really early. I hated the bus.
