Not long after I first took up hunting I ventured out on my own one weekend to a spot called Cannonball Flats. It was named for the round boulders that covered the river flats, rough to walk over but fast to warm up when the sun hit them. A perfect place to look for a deer in spring, when they might stay out on the clearings into daylight, feeding on the new grass. Only, it wasn’t spring. It was early winter and the flats had stayed frozen all day.
