Free domestic and imported lumber scraps.  Our son, Dan, is following his father's passion and making some really cool stuff.  One of his signature projects is a ~2'x3' US wall map made from scraps.  Ideal thickness less than 1" and anything 2" w x 4" l or larger will work.
I'm posting as I would be the one that would be picking up any scraps.  I am retired but would prefer to stay south of Concord and from Manchester east unless what you had justified a special trip.
