I actually read this article in the "real" paper last fall and am just getting around to posting it. This talks about the fishing he did while in Alaska. He didn't visit much of the state during this 1944 trip.
When I think of FDR and Alaska, I actually think of his New Deal program which sent colonists to Alaska in 1935 from Minnesota, Wisconsin and Michigan. The reason is that two of those colonists were my great-grandparents. My grandmother was six months old when she arrived with them.
