Thank you!! These guys are pretty friendly, obviously still wildlife and unpredictable but they don't scare that easily and sometimes just walk up to people, they are very similar to a goat. The males are the ones I would worry about! They have the huge horns and an extra layer of bone/ cartilage built in to their skulls to ram each other, they are actually pretty friendly too. I can't say I have ever heard of an incident yet(not that I have looked)
The Rockies are a little hard to get around in by foot even by vehicle but it's part of the fun. This section is only accessible by vehicle from June until October. I bet it was nice to fly over them, never had the pleasure yet...someday!
