Floating Front Doors

  One of the most curious phenomenon have found is something I call the "Floating Front Door". More than a few houses here have front doors without porches. They are simply floating up there, looking neat and fully functional, with no way to get to them.  My theory is that the houses were built with front doors out of a sense of tradition. However, because of the mud, snow and dirt, most people use their back doors or mud rooms to go in or out of the house.
 The thing that bothers me is that some of these houses are quite old. No one has ever had the time or inclination to add a porch? Am I the only one who has noticed this as odd?  If I were a good photographer I would make a "Floating Front Doors of New England" calender.
