It was very much a wink-and-grin environment: the "bad photocopy job pasted onto a McDonald's gift card" description is very apt. Some bars were tougher than others, but for a guy, showing up with a favorable distribution of girls would cause the bouncer to look the other way.
It's obvious and egregious (UGA suspends open container laws on gamedays), but as the article's subjects and other HN posters point out, the problem is not bars and fake IDs, and more college students' drinking problems. (Which exist at fraternities, house parties, and other venues as well.) To that end, I laud the focus on safety, education, and one-strikes over just pushing the "scene" underground.
