I'll ring but the letter looks like it is set in stone (excuse the semi hysterical pun). The road is used by the school bus that goes round all the small villages and hamlets. We don't use the bus any more because I go into school town anyway in the morning so it is easier (& a lot cheaper) for kids to come with me.
The school bus is often late anyway, so all those kids will turn up very late for exams. It won't even fit up teeny grassy lane short cut so will have to go many miles in a giant circle.
Flight paths, bridges, rivers, road closures - no wonder we are all stressed!
