RE: Trip
Whey the hell didn't you say you were coming through Seattle?  I'm about two
minutes off I-5 when you were passing by Lynnwood, always good for a cup of
coffee.
Good luck on the trip.  Check the weather carefully if you decide to use
routes other than I-5.  101/Hwy 1 down the coast should be clear but inland,
like 395, will be cold and probably snow.  Only real snow issue heading
south on I-5 is the Siskiyous but they are kept clear if at all possible.
