After a brief hiatus, Camp Spaulding in Concord is back, and it’s sort of brand new this year thanks to a creative partnership between Child and Family Services of N.H., the Concord Family YMCA and the YMCA of Greater Nashua (the only such collaboration of its kind in the country, according to Kat Strange of Child and Family Services). The new setup features a day camp as well as the traditional residential camp, and if our visit is any indication, everything gets a big fat thumbs up from the kiddos.
