a $500 fine for drivers who blows above a 0.08

I've said it before and now I'm saying it again: There ought to be a fine for "professional" writers who consistently make errors. Like, say, a $500 fine. The error here - in "Drinking drivers beware" in 24H Vancouver on April 28, 2010 - is the S at the end of blow. A driver blows, but drivers blow.
