In this March 23, 2012, photo a large oil container, bucket, and a bag of trash lay in a gully as semi-trucks pass on Highway 85 near Williston, N.D. Litter has become an escalating problem as the rush to tap vast caches of crude escalates in North Dakota. Some of the industrial rubbish blows in from unsecured truckloads, but for many, the most frustrating trash is the gallons of discarded urine. (AP Photo/Elijah Nouvelage)
