Besides Yorktown, the only AWI battlefields I've been to are in New England and New York. Boston's North End (where many of the events leading to war occurred) Lexington & Concord Breed's/Bunker Hill Ft. Ticonderoga Ft. Stanwix Oriskany Saratoga
Have only visited Yorktown, Monmouth, Castine (Maine) and Ft. Laurens (Ohio), of which I would say Yorktown is the most interesting to visit. However, from a military history standpoint, I find Saratoga the most interesting followed by Monmouth. Chris
