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
