File this one under weird obsessions: People who collect vintage motel postcards. Pictured here: Kirby's Motel in Rochester, N.Y., circa 1970s, from
Guy Clinch's collection
. Also of note:
James Lileks' state-by-state collection, and the Great Postcard Hunt blog. Not quite as weird as the guy who collects do-not-disturb signs, but close.
