every day on Sunny's walks, I walk past a car park/bin store/cycle park
this car park is fenced in and has two massive signs out front saying "NO DIGGING WITHOUT UNIVERSITY PERMISSION, FUCKO" (in slightly more but not much friendlier words)
the reason for those signs is that a little distance under the car park, there are a couple of blocks of several meters of bombproof concrete, in which are buried the carcasses of sheep that the university/UK military experimented with anthrax on back around one of the world wars
