We took his kids to the Airborne and Special Operations Museum in downtown Fayette-nam. (I'll be damned but that place has a nice downtown.) That museum is worth a visit by every American who has even the faintest interest in the amazing and still ongoing history of the Army's airborne and spec ops warriors.
And get this-- it's right across the street from the Amtrak station. NO EXCUSE NOT TO GO. Do it now.
