...and a real badass.
I ran across this little guy this morning when I was on a training hike with my llamas. He was about 3' long at the most. He sure tried to play big and mean, though. He didn't rattle but 2 out of 3 of these that I've seen don't rattle. It's a Western rattler, a subspecies of the Prairie or Great Plaines rattler.
My phone doesn't take very clear photos so it's a tad blurry.
