Tail end Charlie reminds me... I was on a bridge replacement job way up in northeast New Mexico, about 10 miles west of the Oklahoma line. Getting to the site around dawn, I came around the last bend, and there was a (what I thought was) huge bull elk in the road. He stood there and watched me park, but when I got out, he took off at a trot and jumped over the right of way fence. Not long behind him came a cow, over one fence, across the road and over the other. Their calf, though, couldn't make it over the first fence. He would go back a ways, get a running start, then change his mind at the last second. He did that a dozen times, in between running back and forth along the fence. At first, he was making a chirping, whistling sound, trying to get Mom and Dad to wait for him, but they were hot-footing it away from me. I hid behind a road barricade and started imitating the calf's call. Eventually, I got Dad to come back to within about 200 yards, but he was still suspicious. Eventually, the calf went back the way they had come, and Dad caught up with Mom (almost out of sight by that time) and they were gone.
