HWY 17 and 20 in Washington State

[chockwald]

In about a week we will leave Spokane and head west to the coast along Highway 2, which we have traveled before, but will deviate off Highway 2 utilizing Highway 17 and 20 over to I-5. Part of this route is through the famous Methow Valley. Have any of you traveled 17 and 20 in Washington? We understand it is very scenic...some say the area reminds them of the French Alps. At any rate, any input any of you might have would be greatly appreciated!!
