Pennsylvania is well represented at the Academy but there tends to be more traffic to Annapolis, West Point, USMMA etc due to geography. The ratio the year my son applied in Pennsylvania was 3:2:1 to Annapolis, West Point, Air Force. That may work to your advantage especially as the applicant pool increases. It may be good to zig while others zag. The opposite may be true as you head west, I would image competition for nominations would be stiff in Texas, Colorado and California for Air Force.
