I don't usually hang about here, just dropping in.

A friend of mine who lives in the South West of England told me the other day that he's twice seen a convoy of unmarked buses moving people around, late at night. He lives on the A36, which is where the route they were traveling (towards Warminster). On the second occasion, he was able to ascertain that the buses were full of people.

Any ideas?

He regularly sees military convoys in both directions. There was no overt military presence this time. Migrant workers being moved about the country secretly, perhaps?
