Yes and no, they generally hide deep in the woods away from people or are extremely visible on the road but it sort of is common enough to meet them in unexpected places from time to time since we share the trails and walk thru fields. The less popular trails at a certain time of day has more chances of encounters. There is always a chance for bison, bear, moose, deer, elk encounters just about anywhere since the park is really just a big section of forest fenced off and we all kinda mingle. Where they know there is a lot of people like the common areas they generally stay away. I have probably encountered them on trails a minimum of 5 or 6 times but they were a bit further away. I once walked parallel to the herd for like half an hour but they were far enough away not to be concerned with my presence and vice versa.
