A Necedah man was involved in a one-vehicle accident Sunday afternoon.  The deputy said about 3pm 43-year old Steven Nielsen was traveling north on 17th Avenue in the Town of Necedah.  As he turned east onto 26th Street, the 2004 Chevy Silverado pickup fishtailed.  Nielsen attempted to regain control, but the truck swerved across the roadway, entered the ditch, and struck a power pole and phone box causing minor damage.  Nielsen was uninjured.
