A group of tourists visiting Yellowstone National Park earlier this month have been branded 'idiots' after gathering around one of the native bison on a boardwalk to take photos, and refusing the back off when warned of the danger.
A photo of the group (which you can see below) was snapped by another park visitor, Cole Higgins, and shared on Instagram account TouronsOfNationalParks, which calls out bad behavior at sites of natural beauty.
