These animals are free to roam and will and do get in your way as your driving through the parks. SO, please watch out for them, including the little ones too like the Prairie Dogs. As far as the Buffalo are concerned, DO NOT APPROCH ANY OF THEM!!! There have been too many incidents were people get hurt trying to pet the little ones and the big fluffy cows! Watch from a distance, stay in your vehicle and take pictures and please don't stop in the roadway unless you cannot go forward or pull off to the side, we who live here thank you!
