That's Pittsburgh in Pennsylvania.
Well, I was wandering around the outskirts of Salisbury the other week (as one does) and came across this rather sorry looking stone and even sorrier looking plaque:
Closer inspection revealed it to be a memorial to William Pitt:
And he's the man responsible for the name of Pittsburgh, as well as several other Stateside locations, such as - just to confuse you - Chatham County in Georgia.
You see, it pays to keep your eyes open when you're wandering about - you never know what you might learn.
