Mary and I were up skiing with the kids in the UP for a couple of days.  Today we took a hike along the Presque Isle River in the Porcupine Mountain State Forest north of Wakefield, MI.  Ice was just out so the waterfalls were really roaring and the old growth timber made for an incredibly gorgeous walk.  I didn't know this prior but Porcupine Mountain SF has 35,000 acres of uncut forest, mostly hemlock, maple, yellow birch and a few white pines. Can't wait to explore it some more.  I'll be reading up on canoeing the Presque Isle River as well.
