      Every time I sit down to write about another area or special attraction I'm always struck by how extraordinary this state really is. Regions throughout Washington, distinguished by their unique cultures, geology, and climates, make this a land of great diversity. Since the inception of Travel In Washington , I've been keeping a running list of notable facts and features about the state. Here's what I've collected so far; it's pretty amazing. I'll be adding more as I learn about them, and I invite our readers to clue me in on the ones I've missed.
