i live in oklahoma city and i cant find anything under 21 even with google. im over 18.
I am not sure you will find much as you are under 21 and alcohol will limit the places you can attend. I would suggest if you haven't already done so, you contact the people at the following link as they should know whats available in the area.

You would probably need to call venues you're interested in going to individually and ask. Most places will have specific nights of the week where they let under 21 folks in, but it's usually once a week or less due to the need to hire additional security. Googling venue names and "college night" may yield some results, as that is what they are usually advertised as.
