All guidance except the euro puts most of MD and NoVA in the single digits by tonight and tomorrow morning. Euro keeps the single digits above the fall line or even a little more N/W.
If we can see the other side of the warm/relax period by the time we get to the warm/relax period, then I'll be pretty satisfied. Long way off, but seems there's a chance of that.
