Check this website out: http://www.westpointcadets.org/USMA/Map.htm
It lists cadets from each state and their locations. You can find out what people from your area do.
States with many cadets are obviously more competitive.
If you are curious how competitive your district is, just email one of cadets from your area which the website has email addresses of.
Edited to add that I searched and determined there is not a current cadet from our district at WP at all! Pretty depressing overall! Closest one seems to be from about 1.5 hours away (which is a different congressional district). Wow.
If one were to go completely by this information, a candidate might assume that our district has no current cadets when in fact we have ten (only 5 charged to our MOC - others charged elsewhere). I did not know that the data is provided by the cadets themselves, that's interesting and explains why some are not listed.
