We have used the two in one out method for bear hunting for years. Two guys go to the stand..the other guy leaves when the guy is in his stand,,the bear hears the truck or 4-wheller leave and feels that the coast is clear. Deer hunting I don't use a 4 wheeler. I approach my stand like an animal walks through the woods..take a few steps pause for some time, and than resume more steps and pause...humans are the only animals that walk in a staight line through the woods without pausing...this alerts and scares deer big time. Since I quit the beeline walk to my stands and approach more like an animal does my hunting has improved greatly.
