Sad but true. I was en route to Winchester, north of the DC area, when I heard a pilot in a Piper making this request:
"I am low on fuel and need to go direct Martinsburg."
"Sir, I cannot give you direct Martinsburg. That route would take you through P40."
"But I am low on fuel and need direct Martinsburg."
"Sir, if you are concerned about fuel I can give you vectors to Gaithersburg."
"If you give me direct Martinsburg, I won't need to stop for fuel."
"Sir, If you went direct Martinsburg from your position, it would put you right in the middle of P40 and fuel would be the least of your worries."
