Not mid, but 3.2 beer is, I think, still classified as non-intoxicating and if stronger drink is not in the mix, the rules are different. As for proximity, 500' or 1000' sounds about right.
3.2 beer is now considered intoxicating. The change was made way back in 1995. This is why Oklahoma now limits the time frame that beer can be purchased. No more around-the-clock beer sales.
