Kevin--LoL @ scent lock clothes--(good one)-And amen to that rule of thumb.
Years ago Gene Wensel did a whole chapter on this subject in that classic book "One Man's Whitetail"--It put a lot of things in perspective for me.
In my own exprience, I've also noticed in some areas where I hunt, a lot of bucks will travel cross wind, as the rut is heating up, and actually create thin little trails cutting directly across a lot of the major doe trails in the area. These are not necessarily the same trails that run paralel to the doe trails. These other thin little buck trails cut directly across the doe trails.-I've deemed them "cut trails" a few years back, in a small article I wrote about a buck that I was able to kill on one of them. I look for these "cut trails" any time I hunt a new area. I'm sure most hunters notice them, and just refer to them as another buck trail. I like to categorize them in my own mind, so that I can distinguish them, from the paralel buck trails. The bucks will hound-dog these "cut trails", and scent check the doe trails as they cross them. At the same time they are also checking the cross wind.--When they hit a hot doe trail, they take it. ---Don McKellar
