OU, social life, facilities?

<p>Given that OU has predominately in-state students, I am curious as to what OU is like on the weekends. Does the campus empty out as students go home for the weekend? Or do most students stay on campus (and not necessarily physically on campus but stay and maybe even explore Atlanta?) If students go home, what's it like for out-of-staters there?</p>

<p>Also, I know that they are building a new campus center, but I've also seen plans on an architecture firm's website for renovation of the athletic facilities/fieldhouse --I haven't seen this mentioned in any official OU publication/website. Might someone know when the athletic facilities/fieldhouse will be renovated?</p>
