Just after midnight, Station 85 was alerted to cover Lewes Station 2 as they assisted Rehoboth Beach Fire Co. on a building fire. While enroute, Engine-Tanker 85-2 was diverted to a fire alarm activation on Coastal Hwy. at the Achorage Motel. Crews checked that and determined it was a result of the initial working fire around the corner. Crews then proceeded to Rehoboth Station to coverup. Crews remained in Rehoboth until around 0400.
