Unfortunately, there isn't an easy solution to small-town schools because it is hard to get drivers. It's not safe...it's just what is done.
I drove the bus or equipment truck for my groups because we could not get district drivers. The bus driving was an addendum on my contract when I first started at my small school, and it was the only way we could get to places on time. After football season my assistant or I took over doing the equipment trailer because we didn't need 2 buses anymore.
