UP 3687 East
Title:  UP 3687 East
Description:  These guys were finishing up at the Ash Grove Cement plant just east of Durkee when the dispatcher called them, telling them if they didn't hurry, they would get trapped. There were two westbounds coming and an eastbound working its way down the hill. Due to construction on I-84 I missed the first westbound, but caught up to it later.
