Well, when I was still hunting back in Vermont, I would tend to focus on travel corridors around bedding areas during the rut. if igured that the bucks would be shacked up with the does, and that's all they were mainly concerned with at the time. They would run around looking for the next doe to breed, but I don't think they'd go too far.
Once the rut is over, I believe it's all about food. The bucks that have been running themselves ragged for the last few weeks, have lost a ton of weight. Therefore, they will be hitting the food sources hard to replenish.
Of course, when the secondary rut sets in, you can shift back to the thicker stuff if it occurs in the area you hunt.
I agree with Vermonster. Typically, post-rut is when the winter weather starts to come in and deer quickly switch from breeding mode to survival mode. This means they stick to the food sources. They will also tend to feed for longer or more frequent periods of time as browse becomes harder to find and harder to access. While the secondary rut can have an affect, most of those does are still going to be grouped up and near food sources so that would still be a great place to be set up.
when i hunt late rut i start looking for a place to put a blind or tree stand looking over a large thicket or heavly wooded area's because thats when they start to become very skidish and like to be hidden so look for wooded areas and keep your eye's alert!
As a Taxidermist I look at hundreds of Whitetail Bucks every year. I know that I have seen many different ways people judge the size of racks on live deer. I think for the most part they all are pretty close. I'm going to give you some measurements that I have noticed being right on in just about every deer. We have used it in the last couple years and have only been off by about 5-6 inches. We do study the deer while bowhunting so we get a little more time to look at them....
