Check out the USNews website. Sure - their ratings are a load of cr%p, but they have stats on out of state acceptances for each school. Personally, I'm from NJ and was accepted to several out of state public programs (Maryland, Penn State,...). When I applied last year, I evaluated schools on this basis: If it was an out of state public program I only applied to schools where my stats were significantly above the average (out-of-staters typically have higher stats than in-staters), from this pool I applied to the schools that took the most out-of-state students. It worked for me, I was invited for interviews at all public out-of-state programs I applied to but one (Ohio State).
Good luck to you...
