I will be driving across northern Washington State (from West to East) in
another few weeks on my way to Northern Idaho.  We will ake a day and a
half to transit the northern part of the state.  I am debating one of two
routes and am looking for feedback from anyone who knows either route.  I
will be returning via Canada, so taking one route going and another on the
return isn't an option.

Here are the route options:
1.  Route 20 from Burlington/Anacortes east through Snoqualamie National
Forest, North Cascades National Park Okanogan National Forest to the Grand
Coulee Dam.
2. Route 2 from Everett east through Snoqualamie National Forest, Wenatchee
National Forest, Leavenworth to Spokane.

Which one is more worthy?  Is the Grand Coulee Dam worth a detour?

TIA
