We have a 160 acres in SE MN. We hunted for 5 years and killed the first buck we saw. In 2001 we started passing up anything under 130, by 2003 we were where seeing the results. We have now taken at least one nice buck a year since. Not everyone around passes on little ones but with only 160 acres it still works. Keep the pressure low and have an area that you don't touch EVER! watch for dogs and coyotes. A dog maynot kill a big buck but if it bothers him enough he will leave the area. By the way you probly have a big buck around and just don't know it. Good luck!
