Unpredictability. (Is that a word?)

This morning more than the average number of high school students rode the bus and inversely a less than average number of elememtary students rode. That just underscores the unpredictable nature of driving a bus. One moment you are driving along and everything is going just fine and then boom it hits. Something happens that could not have been predicted that you must deal with. You have no choice on a bus. There is no one else to deal with it. Just you. On another subject, I wonder when my district will look into the possibility of buying a new plug in hybrid bus. Short route school buses would seem to be a perfect fit for that new and emerging technology.
