Ouch. Is it possible for you guys to head down as normal and Dh meet you there. I'm in the Philly area and while we are predicting about 6 inches, they are saying this will be a fast moving storm so hopefully by Sunday every thing will be plowed and sanded (sp).
Philly international is pretty good about staying open, of course it will have problems if incoming planes from storm hit areas can't make it.
First, I would call MS and update them on the potential problem. See what they have to say.
Not sure about trading into the Poly, some one else hopefully can help with that.
