When buying gas this morning, I noticed the crew cleaning up the local superamerica was using one of those billy goat walk behing vacs. He was picking up from blacktop and the unit seemed to leave at least 20% of the leaves behind. What was funnier was the his helper trying to blow the leaves across the parking lot into a 15mph wind when there was nothing but open land on the other side of the lot he could have been blowing them. Hahaha! Some just do not get the concept.
