The age old question around the N.W. is; "What Happens if it rains"?
Here's the deal:
Unless a horrific front moves in that blankets the whole N.W.(Western Washington and Eastern Washington and Idaho) which is extemely unlikely we are "good to go". All you need to do is get to Issaquah. You guys that have rag tops and hard tops can gloat at those of us without, but we will go anyway. We have 3 chase vehicles, all are 6 passenger or better, so wives, SO's and the weak at heart can load into those for the trip across the pass. Once past Snoqualmie pass the weather will moderate and we can re-arrange the seats. Drivers in open cars, like me, will just have to tough it out. I've done it before, will bring rain gear, "Rain X" and know that it will dry out on the East side.
Too many times around here, the weather looks bad and then changes. A case in point was last year's Skagit Cruise. The day started with a thunderstorm here in Mt Vernon and solid overcast and rain in Seattle/Tacoma. By 10:00 A.M it was a perfect day (except for Slad Daddy whose EFI died) and we had a great drive.
So we will keep an eye on the weather satellite pictures, but unless a monsoon sweeps in........we go.
