Rocky Mountain bighorn sheep favor steep and mountainous terrain, which means they hang out in places that are hard for humans to access. But at the Georgetown Bighorn Sheep Viewing Area, looky-loos can pump a few quarters into the giant binoculars and take a gander at the hundreds of sheep that make up the "Georgetown herd." One of the best times of year to spy on sheep is in November, when the town hosts the Georgetown Bighorn Sheep Festival. It's also the species' mating season, which means visitors are more likely to see male sheep head-butting each other to establish dominance — and for a shot at makin' it with the ladies.
