Rena, WashingtonRena is a former community in Clallam County, in the U.S. state of Washington.HistoryA post office called Rena was established in 1891, and remained in operation until 1902. The community was named after Reena Hooker, daughter of a local settler. A school operated at Rena from 1888 to 1912, and the town remained a "recognized community" until about 1915, when the land was bought for the construction of a mill. The mill changed hands several times before ultimately closing in 1967, by which time Rena was no longer recognized as distinct from neighboring Carlsborg.
