Actually ain't is a word now, has been for years. I want to say it was mid to late 90s when it got added to the dictionary.
That being said, they said more than twice the legal limit. He was pushing .20, I think it was .196 or some shit. Each .01 is a pretty big jump in how much you have consumed and how drunk you are. Even for a pretty big drinker .16 would be pretty "buzzed" at the very least if that's what he was at but he was closer to .20 from everything I read. Also that's what he had to drink at THAT bar. I used to watch Viva La Bam all the time and those fools would constantly drink throughout the day so who knows if that's all he had to drink, that's all speculation though. Either way he was driving legally drunk, well over the limit actually, and speeding up to 140mph in a 55. Sucks he died, dude seemed like a nice and down to earth guy from all I read and have seen on tv through the years, but it was his actions that cut his life short and that of someone else. There is no one to blame but Dunn.
