			Mark Humbert makes a delivery in his final 
			week of working for the USPS. After a million miles and 30 years 
			later it's time to park the LLV. 
  
			
			
			  
			Here he is filling the cluster boxes at 904 
			21st St. One of his many trailer parks on the route.

			Humbert's route is not entirely a mounted 
			route. He has to deliver the trailer parks, too. Here he is at 904 
			21st Street unloading his truck for delivery. |
