"I walked 3 uphill miles in the snow to get to school!" Many of us have heard these tales, but in my Dad's case, it was true. I recently visited the site of his long, meandering, nature-filled path to and from elementary school. And the stories of his scholarly treks were infused with mischief, adventure, and at the end, one giant appetite. But these days, fewer kids use their feet to get to class.
