Here in Basehor it is common for bus drivers to keep their buses at home. It makes sense. They can warm them up in the driveways a lot easier during the winter and they can keep a closer eye on them. If you keep all the buses together, you run the risk of multiple buses being damaged in a short time by vandals. It would be easier to slash tires of several buses, then you're in trouble trying to scramble and school would probably have to be cancelled. At their homes, that couldn't happen in large numbers. Think about it.
