From what I understand, every year at the end of September there is a round up of the buffalo herd. I think this year it will be on Friday, September 27. We will be visiting the park on the 25th or 26th. I was really hoping to be able to see the buffalo out in the wild, on the road, etc. Are they still roaming free prior to the round up where this might be possible, or is there some preliminary marshalling of the animals prior to Friday's drive to the corrals? thanks for the help.
