Yes, that's what I'm talking about. It's possible that things have changed since I was in college ;)

You can use the temporary drivers licenses as driver licenses (for actual driving), but I don't think they are generally accepted in other situations.

Once upon a time, it worked very well.

Once upon a time, alcohol usage among college students--regardless of age--was something that a blind eye was mostly turned to, including most local bars and the like to say nothing of the college itself. From what I can tell, this has mostly changed a lot.
