I lived in Western Pa until I was 12. The French and Indian War as we call it was an important part of history there. A couple of years ago we visited Fort Necessity on a trip back to Michigan. Much smaller than what I expected and what I thought I visited when I was 8 or 9. Turned out my visit way back then was to Fort Ligonier, another 7 year war fort built by the British.
I also spent a bit of time touring around Point State Park in Pittsburgh, Another Seven Year Fort.
