Nope, an Oxford tradition - following the departure of the Miami students.
Just noticed this, basically when the Miami Students leave, they can't take a bunch of nice stuff home so they throw it away. Basically dumpster diving, Luke convinced me to try it.
In other words, spoiled rich brats throw out perfectly good stuff, knowing their 'rents will buy them new for next year. I guess in a sort of bass-ackwards way, it's charitable...
