I think anything halfway would be five hours or so. And it would depend on whether you went through NY or up through CT and MA. But it IS probably too late.
I kinda wish I had a few decent maps, for future use, in any case.
Sigh... according to Mapquest, NYC is about halfway, and wouldn't THAT just be fun - not if I'm driving in.
Darn, why must my brainwaves always come too late?
