My county would pick up all of the kids in the same neighborhood on the same bus (5-18 year olds) and the kindergarten kids always fell asleep on the way home (we were about 30 minutes from the schools, but they got picked up first and had to sit through the middle and high school pickups as well as the trip home). They always took forever to get off b/c usually mom had to physically get on the bus and carry them off in the afternoon!
