1. Washington - all over the state, lived there for a total of about 12 years throughout my life
2. Montana - Mostly the southwestern portion, have lived here for the other 15 years of my life and am here now
3. California - Went to Disneyland and stayed here for about a week
4. Wyoming - Been here a few times to go to Yellowstone National Park
5. Oregon, Idaho, Utah, Nevada, Arizona - driven through en route to other places

That's it. I have never been out of the country and I have never been east of eastern Montana.

I have also only been on an airplane once in my entire life. Well, twice, I guess. It was round trip.
