The big Rams and Bucks stay away from the people. I have seen some nice animals but it requires getting away from the roads and nice optics. I love Antelope Island. Yellowstone light, and by far the best state park in Utah. It is underappreciated and underutilized. If you take optics, especially in the winter, you can easily see deer, sheep, antelope, bison, porcupines, hawks, eagles, falcons, a diversity of songbirds, pheasants, tons of different migratory birds, chukar partridge, coyote, rabbits. The wildlife viewing is better than Yellowstone. Amazing place.
