parking slots

if you look at where the parking slots are located a KSCH and you look at the actall airport layout you will notice that they are all on Straton Air Natonal Gaurd Base. with none on at Fortune Air or The Richmore Hanger (where civilan aircraft are actally parked). dose this make sense. also something else that dosent make sense: i was on final in a F-15 when i go and request landing clearence at andrews airforce base i am told to go around becuase of a dehavel dash 8. what is wrong with this pic???
