Take a tour of the NH State House!
NH has an inordinately large number of micro- and nano-breweries and we definitely recommend checking them out! The link is for the NH Brew Map. We also encourage you to visit our favorite meaderies: Ancient Fire and Moonlight Meadery.
Nothing says fall in New England like apple picking and cider donuts!
Museum built in honor of Christa McAuliffe (first teacher in space) and Alan Shepard (first American in space). There are interactive engineering and science exhibitions including a full size replica of a Mercury Redstone Rocket.
We would be remiss to not tell you about Wow Chicken, which is within walking distance to the recommended hotels. Phil feels the need to go here any time he's in Concord (which is relatively frequently). Get the shawarma.
