Yes, mature bucks can be patterned in highly pressured areas. I get it done every year until Sept. 15th. LOL
I hear what Duke and Cougar and some others are saying, but I feel there is a big difference between hunting pressure, and people pressure. A lot of the areas I hunt are frequented by motorcycle riders, joggers, dog walkers, horseback riders, mountain bikers, and hunters. I see how the deer react to the people pressure and that is they are attentive to it, avoid the people, but then go about their business. They react much differently to hunting pressure. People pressure will alter the deers' movement in the woods, hunting pressure puts them on lock down.
I've seen it every year over the last 8 years since I moved back up here. There is a difference. That doesn't mean those bucks can't be hunted, but I have found a tried and true method yet.
