MINNEAPOLIS -- When the morning sun peeked into our camper cabin at Whitetail Woods Regional Park, I almost thought I'd awoken as a bird. My nest was, in fact, a boxy, mod bunkhouse, cantilevered into a stand of evergreens. I looked through the cabin's glassy back wall and watched the thin, towering trunks sway in the barest breeze. I never would have noticed their invisible rhythm if not for my uncommon perch.
