NORTH WOODSTOCK, N.H.—On a clear, frigid night in a courtyard made of walls of ice, Bruce McCafferty and his young son stand mesmerized, bathed in the pulsating rainbow light emanating from a series of stout ice formations.
McCafferty and his son Dougie have come out to Ice Castles in North Woodstock, New Hampshire, a collection of ice tunnels, caverns and a 97-foot ice slide that covers an acre of farmland that some have said are like something out of the movie “Frozen.”
