wonder what the line they will use when it crosses the average? it is getting closer and closer. Trend is down boys!
It need NEVER cross the average! When it's about to, they just go shopping for a time window, the average of which is still lower than the current temp, then THAT becomes the threshold. Kind of like when MADD got the federal BAL lowered, then as soon as it went into effect, cried far and wide about the "increase in drunk driving". (BTW, how's that for a ludicrous phrase: "federal BAL"?)
