Reminder: It’s not winter…

Despite all the bellyaching over “unseasonably low” temperatures this summer, it’s not as though Lake Superior has frozen solid.

But, if the autumnal weather did spawn visions of augers and tip-ups dancing in your head, check out photographer David Friedman’s profile of Tom Roering, inventor of the Wilcraft, an amphibious, convertible ice house.

The company that makes the Wilcraft is based in Maplewood, Minn. Friedman’s other [inventor profiles]( are worth reading and watching, including one with Art Fry, inventor of the Post-it note.
