I'd hit up an Ivy league school for sure.
Notre Dame, Alabama for football
Duke, UNC, Kansas for hoops (I've already seen UK)
I've seen Pepperdine and it's all its cracked up to be. Been to UCLA, odd campus.
If you want to see some really cool campuses you can look into the D2 route as well. Seton Hill in PA was spectacular. Belmont Abbey in SC was fantastic as well. Small private schools funded by religious orders are often very nice.
