-I agree with Ychennay, another piece of evidence is in "Ten Sessions" when Stella says she went to Stanford and Ted says "Wesleyan" for himself.  Not Ohio Wesleyan.  Not only that, but remember in "Arrivederci, Fiero", when they are driving back home for the holidays, and Marshall offers Ted a ride to "pick him up in Ohio" on the way back to school from Minnesota, because he wants to save on gas money.  Well, that presumes they are splitting gas from Ohio back to Connecticut, not Ohio to Ohio.
