So they are short bus drivers and had to rearrange bus routes because of that shortage and now that they have been rearranged more kids will going to be walking to school. Now your going to take bus drivers off the route to be crossing guards and make it even less bus drivers to pick up kids. Why not just sell the buses, fire the bus drivers and hire for crossing guards. It seems that is where your headed. Make money all around.
