'X' is for Xmas Pie.
X is one of the letters that we are having to 'fudge' a little, as we can't find a place (eg Normandy) or feature (eg Hog's Back) starting with an X. In this case we have gone with the common abbreviated spelling of Christmas Pie "Xmas Pie".
At the starting location is 'the' name sign with a phone number on the rear ABCDE-FGHIJK.
