Our lease consist of 2000 acres of timber and pastures for cattle. The cattle owner rides his atv around 4 or 5 times a week checking on his cattle. I too ride my atv around on the property to check for deer and sign all spring and summer long. It doesn't seem to bother the deer too much. I also turkey huntthis same property, so I'm out there 10 or 15 times in the spring walking around locating and calling. We also have 3 ponds stocked with a ton of fish. One pond is 13 acres and 40ft deep in the middle. I like taking the boat out almost every other weekend during the late spring and summer. We have been doing this for years and I've never noticed that it bothered the deer in any way.
