I'll swap lessons for beer keep to the Fen Causeway
Back in '91 my wife and I went exploring in the then just recently former GDR for 2 weeks. In one place we came across a gang of workers who were assigned to repair a water main, which they didn't know where it was.
So one of the guys was quartering the area holding two pieces of coathanger bent at right angles loosely in his fists so that they pointed ahead of him. Whenever he walked over the pipe (or at least some underground water) the pieces of coathanger would cross.
It never works for me but it does for my wife. Go figure. The fact is that what we're experiencing right now is a top-down disaster. -Paul Krugman
