Keith,
You are confusing our O/S friends no end
.
Yes , the back yard blitz ..we all have them .
For the uninformed ..there is a local TV show here titled BACK YARD BLITZ. A team of people turn up at somebodies residence, unannounced. The victim is usually a 'down and out' hard luck story person . They spend a whole day renovating the back yard , garden or whatever. In my time , I've seen a few back yard catastrophes , usually it is a single male with a MV collection.
