I visited Ft Ligonier several years ago and I have to say I was impressed. Not only does it interpret the French and Indian War in America but also has some fantastic artifacts from the world wide Seven Years Wars. They also have the most extensive collection of reproduction period artillery I am aware of anywhere. The town itself is very quaint with shops for the wife and a Toy Soldier Store.
Highly recommended if you are anywhere near there. Glad to see that its getting more attention.
