Agreed. My place is not too far from where this happened. All along the front range in central & southern CO it is just a fact of life, the weather is unpredictable. Well, more difficult to predict than in many (most) other places. These kinds of storms are nothing new, they happen almost daily during the southwest monsoon season, and at least a few times in the spring each year too.
the lack of animal injuries maybe indicate they are the smarter ones (as in getting in OUT of the hail)
