If you've toured Concord, MA, give me your impressions, please. I've wanted to visit there for years and thinking about actually doing it this fall--mid to late September. It looks easy to get around to any point of interest of your choice. I've been to MA before (and all over New England for that matter) just not to Concord. I know to fly into Logan and take ground transportation into Concord. I know what I want to see.
So...how was it for you? What were your "must sees"?
My personal "must sees" have to do with Thoreau, Walden Pond, and other historic sites. Okay, it's mainly Thoreau.

If you have something to share, please do!
