450 miles. That's the distance Marnie Mamminga's family traveled every summer from suburban Chicago to their cabin in northwest Wisconsin.
Mamminga recalls the cabin, and the long journey it took to get there, in her latest book Return to Wake Robin: One Cabin in the Heyday of Northwoods Resorts.
In the 1950s, America's Interstate highways weren't completed, so Illinois families headed "Up North" drove rural roads for much of the trip.
