I grew up in a relatively poor midwestern school district. Our school buses were kept in the city yard with a night crew of mechanics. Around 0600, the drivers would show up in their personal vehicles, be briefed on weather conditions, and drive the buses out of the yard. Buses back by 1800, and gone over thoroughly by qualified mechanics before being released for next day operations. Did I mention that this was a poor school district?
When I moved to Saint Mary's County, I was amazed to see school buses parked in the front yards of homes (presumedly the homes of the drivers), usually with a passel of hound dogs sleeping under them.
How do maintenance and operations logs get appropriately fullfilled with such backwoods operations? Has the water been bled per schedule from the fuel filter/separator and the air brakes? Tire pressure measured every morning? My guess is, 'no'.
I have not yet been blessed with children, but when that day comes, I would never allow them to ride a Saint Mary's County school bus. If those kids are going to be driven to school by someone with a stinging hangover, it's gonna be dear old dad. And they will get there in one piece.
