Apparently this season there has been a series of injuries in Yellowstone National Park.
A woman turned her back on a bison in order to take a photo of herself with the magnificent beast. The bison charged the women, throwing her into the air.
Seriously though, four other tourists have suffered similar fates this year.
As a result, the Yellowstone National Park officials are advising against attempting to take a selfie with a bison.
Just so you know. Read about it over at BBC.
