What do you do for entertainment when you bring your teenage son and his best friend to visit your parents, who live in a tiny rural town, and it’s only 20 degrees outside? You hike through a frozen bog on a boardwalk, of course. I love the almost alien feel of the landscape as you move deeper into the bog. And the boys had fun hacking at ice. They weren’t even too disappointed when we refused to let them walk past the Danger sign out onto the icy stream at the end of the boardwalk.
