YADDA New York's Penn Station
Yet Another Door Distribution Again. Doorway to a train track at New York's Penn Station showing the two halves of nearly circular bell-shaped curves of wear. But from what? Most likely the edge of Amtrak luggage carts pushing the door open. The carts seem to push equally on each door, with perhaps a slight bias for the left side. Compare this to the bookstore doors or the Dulles airport doors from earlier posts.
