The Scottish Play.....

Say from whence
You owe this strange intelligence, or why
Upon this blasted heath you stop our way
With such prophetic greeting. Speak, I charge you.
Macbeth I.3

On the way to coffee with a fellow MRCS examiner, I let the Satnav find the way.   Across this blasted heath.

In Extra:  Then it was on to Rotary.... guess what the talk was about.
