Guilford Courthouse NHP is excellent. A great reenactment as well, and heartily recommend it! See the adjacent Tannenbaum Park (county or city) with the Hoskins house and related buildings, museum, visitor's center, etc. There's a mill outside of Greensboro where Lord Cornwallis "got his corn ground" (richt weel, no doubt)as he approached Guilford Courthouse (reference to a disgraceful song of the period!). They still grind corn, barley, etc. on site and it's fun to have bread, etc., made from grains ground in the same mill. Someone else will have to chip in with where it's actually located as I can't remember.
What a wonderful trip, in any event!!! You can't help but to enjoy that area!!!
