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.

Giving Rambler A Bath

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.

Although the caption reads Southhampton, David Greenlees of The Old Motor says this is actually Hampton Bays, Long Island, New York, and that the old motor in question sports a London to Edinburg touring body. I suspect indecent amounts of money would be involved in all cases.
