OU Visitor Center

At the Oklahoma State Visitors Center when you enter the state from Texas there was a book on visiting OU and taking a tour. After reading it and growing up next to a diehard OU alum I called up the number and inquired about a tour. They were very helpful on short notice.
When my Dad and I got there we were greeted and they made us feel welcomed. We were mistakenly put in the tour for prospective students and taken all over campus. The student tour guide knew her stuff and took us everywhere. In and out of class rooms, dorms, offices, reading rooms and more. She answered our questions when we had them and even let our group take a break here and there. The tour was a blast! When we got back to the visitors center after the tour was over the staff was nice and helped my Dad and I find our way back to the student union for lunch and where to buy t shirts and hats.
If you have 3 hours or so and want to go on a neat walking tour filled with history, culture and people facebooking on their cellphone while riding a bike through campus then you should take the OU tour.
