My fiance and I are making the move from here (the border of NY/MA) to the Seattle area. We're probably leaving around the 6th or 7th of January and hope to be in Seattle by around the 12th or earlier.
Has anybody made this trip, or one similar, in the winter? We're planning on hitting I-90 and not doing a lot of sight-seeing on the way... just concerned about road conditions and places/passes we may want to avoid.

If you have any suggestions or cautions, I would appreciate hearing them!

Thanks :)
