Well there's two thoughts on that for me:
1) If I decide to play the commuting game I'll pick IAD...there's over 9000 flights a day from where I live to IAD but the crash pad situation isn't as good as STL.
B) If I want to live in STL I could arrange a rental house with a few friends in the college areas and re-live my lost youth. Too bad I'm not single since I've become all aesthetic pleasing to the women-folk.
