coupla posts on here about that with some varying opinions - my experience has been no real problem as long as it's in a cup (commonly referred to in these parts as a "Haul your ass" cup) and you haven't had enough to impact driving skills. Personally I prefer to let someone else do the driving so I can do the drinking, so your plan sounds good to me!

I can never remember which is better . . . safe? . . . or sorry?
