MEDORA, N.D. (AP) — The day his young wife and mother died, Theodore Roosevelt wrote in his diary that “the light has gone out of my life,” and it was only through extended trips to the isolated Dakota Territory in the 1880s that he regained “the romance” of living. A library examining the country’s 26th president will open next summer in the North Dakota landscape remarkably similar to what Roosevelt would have experienced: far from any city and surrounded by rugged hills beneath a vast sky.
