These pronghorn were a ways off, but moving frequently. At times they took off in all out sprints, and I was able to capture these three in stride together. This was captured out at Antelope Island State Park in northern Utah.

I really like this one John. Great timing and spacing on those three. My attempts at running pronghorn all end up being "artsy" motion blurs. Although I personally don't mind the BG bushes on the hill, I think this one would work pretty nicely as a pano as well. Nice image.
