This is sort of a spin-off of the "Noticable changes to the set" thread. In the old days of the show (pre Season 30), each end of the street had a backdrop flats that depicted a continuation of a city street, thus making Sesame Street seem longer than it actually is. I'm sure that if that were actuality, then there would be several different ways to get to Sesame Street. Since Season 30, however, this hasn't been the case: one end of the street is blocked by the subway station, and rare shots show that next to the subway is a flat of other store fronts, making the street like a dead-end, while the other end is blocked by an aging brick wall, and also in rare shots, that wall is boarded by a long wooden fence... which would make the street like an isolated private community or something. One would still be able to get to Sesame Street via the subway, but how else could anyone get there with a brick wall and a long fence in the middle of the road? How have buses and Oscar's Sloppy Jalopy and whatnot gotten in and out of the street?
