The first National Park in the United States to be dedicated celebrated a birthday to start the month of March. March 1st marked 150 years since the establishment of the most iconic of American National Parks: Yellowstone.
I've seen multiple videos in the past week and they're all inferring the same thing. Bison are running from the park because Yellowstone is about to blow.
If you grew up in South Dakota, Nebraska, Wyoming or North Dakota there is a picture of you riding a tortoise at Reptile Gardens. It's an 8 decade tradition.
