.. I wouldn't go to Oregon though, I'd be worried about cloud cover being so close to the coast, and earlier in the day...
It was a much bigger deal for people than I realized it would be. Maybe because it's been so long since the last one in the US.
Agree with you on the Oregon coast, however, there is a "rain shadow" east of the Cascades in Oregon - similar to the Eastern Sierra but without the afternoon thunderstorms. Turns out to be the lowest probability of clouds in all the areas shown below. Sunshine 300 days a year. Did my homework, I'll be, in Madras Oregon, along with NASA. Backup plan is to head further east to more desert. Nebraska looks like a good choice, you'll get 30 seconds more totality.
The Europeans were on to this way in advance of Americans. People are coming from all over the world for this, and you're right, even small town motels and campgrounds filled up a year ago or more.
