It is now four years since I first asked for support, and I would like to sincerely thank everyone who has helped me. BrainBashers doesn't show adverts, and I continue to depend on the ongoing support from everyone who enjoys the site.

I was travelling from Chesterton to Newcastle recently when I came across a sign which had fallen off its post at the crossroads.
It was marked to Newcastle, Chesterton, Knutton and Silverdale.
Unfortunately I didn't know which road to take to Newcastle and had hoped the sign would help.
Luckily I had a brainwave which helped me put the sign back pointing correctly to Newcastle.
What was my idea?

Hint
How many different ways could the sign be placed back?
