I am from Ohio so I know a bit about some of the campuses. I visited OSU, OU, and BGSU for my undergrad, and have visited friends there since.
OSU wasn't for me - downtown Columbus and a very large city campus. It was a little overwhelming since I didn't grow up in a big city. Columbus is a really cool city to visit though, with a lot to do - sports, concerts, arts, & the zoo! I have heard from SPHS undergrads there that the graduate students aren't super impressed with the program. My friends in the undergrad program just didn't even apply there...
OU is a really pretty campus & a little more of a smaller city feel (but still plenty to do with outdoor activities, bars, restaurants, sporting events). Athens is south of Columbus so that could still be a fun day trip. Hocking hills and other places to hike, bike, horseback ride, canoe, etc. are all near campus. I have a couple friends there now and they seem to love it. I feel like I remember someone saying they don't help you as much with your grad externship placements, though (not 100% sure).
BGSU is farther north, almost to Toledo. One of my best friends went there for 2 years so I visited quite a bit. Probably the smallest of the towns of the three, but plenty of good food and bars still. We went up to the mall in Toledo for a day as well, since that is about an hour drive. BGSU seems very focused on the more educational side of everything - tons of my high school classmates went there for elementary, special ed, etc. I didn't particularly like the campus; it isn't particularly pretty or anything but my friend that went there still seemed to enjoy it.
Hope this helps you out a bit!
