Great too see that you got out to antelope island. If you get to spend a little more time out west, and drive arround eastern wyoming much you'll see litterally thousands of proghore or as the locals call them, Speedgoats.

Just an observation, those shots look way over cooked in PS. I recomend that you back off the sharpening just at the point you start to see that halo. In those shots, the halo is huge, which tells me that they have been way over sharpend.

Good luck and keep photographing wildlife!
