Pacific Northwest A-V8

Proud Scandinavian motorhead and hot rod Ford in quintessential Olympic Peninsula Washington State setting - river valley prone to winter flooding with escape route climbing into dark forest. Before all the vampire stuff. Or maybe not.

1951-2 Nash Rambler Convertible in mystery location, although I believe these folks were from the Maryland Virginia Pennsylvania Delaware area. Looks like a fairly unusual spot. Any clues would be greatly appreciated.
