If you are talking just Gene and Barry, they have been established in Iowa for over a decade and have access they have work hard to secure. They also commit a great deal of time to hunting and do not want to over hunt a given area. My brothers and I have done the same in Illinois. Access is kind of dynamic in that it changes from year to year, but me personally I focus on my best several hundred acres. Some could say we brothers of the bow are lucky, and you won't hear us disagree, but we are very committed to this way of life and it is what has brought us together. Many chapters in Gene's and Barry's books describe some of the properties and resources they have worked to get permission to hunt on.
I have written about "home body" bucks that tend to stay in one area most of their life. Gene has written articles about bucks that tend to travel more. But no matter the place, its great to just be able to be in the woods with mature deer. That has always been our goal and the Wensels goal. They even moved to a new state to to be able to do that.
