2-3 beers. That's the answer every DUI driver gives to the cops when asked... being a career drunk isn't really something anyone should try to be, I know - I tried it and have been a friend of Bill W. since 1998.
Which leads me back to the point I was trying to make - my point is they (the cops and the victim representatives) WILL throw the book at you no matter how well you have built a tolerance to alcohol. You will not get the opportunity to demonstrate in Court how well you can handle the "2-3 beers" rather you will be judged as impaired because the standard isn't you, it's either the reasonable person standard or the numeric standard (BAC) which will convict you. The only thing that alcohol does for you in Court is make the penalty far worse and the potential losses exponentially greater. John Q Public is tired of hearing someone tell how they "accidentally" had too many or that "they are good drivers, even when drunk." Our justice system does still allow lynching of perps and if you had alcohol in your system, it gives them the right to take it all away from you.
What would be a terrible tragedy of someone being injured or killed on the trail becomes a bankrupting, felony-inducing issue where you were right - and you can repeat that mantra to yourself while in your jail cell - "it wasn't the alcohol that caused the accident." That is correct, it was you and you, according to the law, were impaired. Seriously, it's not worth it.
