I and an older than me friend, used to be on a lease with 2 other guys younger than us. My friend and I got to talking about how much easier at our age if we rode our 4 wheelers to our stands, and if it would disrupt the deer. I told him that I didn't believe that it would as we were hunting on agricultural land, and the deer were used to hearing and seeing, tractors, pickups, 4 wheelers and such, and the only thing in the woods that was unusual to the deer, were men walking in them once a year.
Well, we started riding right up to our stands and getting off and in the stands. We didn't even try to hide them. Both of us continued to kill our three deer each, (one buck and two does) while the other two guys continued to walk in, and kill their one deer (MAYBE) a year. Naturally they blamed their bad luck on us running the deer out with the noise, and pointing out our success did no good. We later lost the lease to the big money Dallas Texas boys, and my wife misses the venison as do I.
