I slip in as its breaking light. On a heavy frost morning about an hour after daylight. Unless I'm hunting a cutover with a SE facing ridge. If you have time and plan on going in later, walk SLOW. Take two or three light steps and stop. Wait a few seconds. Listen. Walk a few steps. Stop for a minute. I've killed a few coming to check me out. I know it sounds stupid,but it can work. Figured it out hunting some steep hills on my Dad's place. Just kind of a hail marry thing I do every now and the late in the season. Works best if you walk below a ridge.
