In the Winds a week ago, I ran across two guys in their late 50's who had been bping together for quite some time and were old friends from grade school, even though one lives in Pinedale, WY and the other still in NH. They had two llamas, I guess borrowed or rented and said they were herd animals so you need at least two at just about all times. On their trip, at one point, one of the critters was ahead with one of the guys and got too far away for the other llama so started crying. The one was pretty gentle, but a little timid.
