Just spent two days at the Making a Great Lake Superior conference here in Duluth, with a few hundred scientists, educators, government folks and some just plain folks. The single-most discussed topic was climate change in the Lake Superior region. As pie-in-the-sky optimistic as I can be, there wasn't much good news, at least in terms of winter outdoor recreation. The models agree that it will get drier and warmer on the North Shore over the next 50 years.
Now would be a great time to open a business offering guided canyoneering trips along the North Shore rivers.
