Clublights- I agree 100%, that's kind of the point I was making... the system isn't perfect, but it's the way it is, because, well, we have to have something tangible to gauge levels of intoxication and people more experienced than you and I came up with this stuff. However, so that it doesn't appear I'm coming from a position of complete ignorance, I did smoke weed in my youth, and I'll tell you, nothing is worse than smoking up, watching 4 hours of Cops (it was a marathon or something) then someone brought up the idea that I, the only licensed driver in the house, drive everyone to a party... Thank you NO! Are you insane!?
