Will we get to Portland for Xmas?

Last day of work is Nov 7, 2014. We plan to hit the road on 11/15.  We are hoping to make it to the Wilsons for Xmas. Not a leisurely journey but not super-rushed either (we have 6 weeks). We plan to take the ‘southern route’ (down the east coast to route 10, across to route 5 in CA, and up to Portland). This could change depending on weather. Luckily Bill is one of the world’s best weather forecasters.
