Interesting! As always I struggle a bit which places to include in such a quiz. It is mainly by population and a few famous ones such as Gettysburg. Sometimes I have to drop a place if it is too close to other cities on the map (here e.g. Hershey and Bethlehem).
Regarding New Castle no very special reason. I am open to suggestions regarding cities that need to be included.

Done, added Wilkes-Barre. Thanks for suggesting this city!
