If you scout in March, look for the large Rub lines and sign post. Bucks in North Missouri are traveler's, they cover miles during pre-rut and rut. These deer will mark as they travel, but could take a few days to make the route again. Public ground does get more pressure, but if you hunt the far edges, on the big buck routes, you can catch them as they return from Private ground. My pick would be Nov-1 and up until our Rifle begins, rattle and grunt and sit hard and long. The mature bucks are not beating a path back and forth on any trail, always try to catch him making his routes. Fountain Grove WMA as mentioned, and Yellow Creek WMA are two that I am familiar with and have Giants walking them.
