I'd be in for this. And don't mind helping with some planning.

One of my favorite drives is to take Mt. Baker highway from Bellingham all the way up to the ski lodges. And there is a huge parking lot up there where we could easily park like 150 cars.

But really if you head east from almost any point on I-5 you will find some awesome driving. I hope some more people get interested in this! I'd love to have a big PNW GTG
