There was a big showing as far down into Washington in Nov 21. Spokane, where I was living, managed to get a great show.... But it just so happened I had to travel to King Co. that week and there was nothing but clouds to see on that side.

Just as a heads up, it's somewhat of a short notice thing, and even then, some predictions can end up being a false hit.

What I'm saying, temper expectations. And assume you'll be disappointed on a decent amount of attempts. Make it an enjoyable experience besides if you catch the lights, so you don't just get discouraged from further attempts
