I was helping my son set some traps this afternoon and saw where at least some of the bucks are...they are with a single hot doe pushed out in the middle of no man's land. I saw bucks where a person wouldn't even dream of hunting (brushy draws in the middle of corn fields). One hot doe before being pushed into one of these areas makes a person think it couldn't get any better, but then the next time on stand it may be really quiet if he gets her out of the thick of things!
A few years ago, my brother was out visiting from PA to pheasant hunt. He left sometime the first week of November, and the day he left, we watched this really nice buck breed a doe out in the middle of a picked bean field away from anything that looked remotely "deery". A week and a half later I shot that deer (he ended up scoring 172). One of the things I think can be forgotten is that during this "lock down" stage, a buck isn't with a doe for a very long period. A buck may spend up to 3 days (according to some studies) with a doe, but in that inbetween time he is on his feet looking for another doe to breed.
