You're talking about a very specific group of people traveling between Tri Cities and Seattle. There are also people out there traveling other routesSorry. Oops, I must have read that into the post. Unfortunately, this still doesn't alleviate ICEing in Ellensburg. From Kennewick, travel to the Seattle area requires Ellensburg (yes, it IS uphill, against the wind, and we do get below zero temperature) and with the M3, there will be even more need. Adding Snoqualmie or Moses Lake, while useful, are not as well situated as EBurg. I've been traveling between the Tri-Cities and Seattle for over 50 years and almost always stop in EBurg, unless bringing my own food and stopping at Rye Grass or Indian John rest areas.
