I know how hard it is to be away from your family as they get older. I lived quite a distance from parents for work, but it was always nice to get to see them. Smoking definitely didn't help your poor uncle, one of the worst health habits there is. Is he still in the hospital?
You took so many beautiful pictures, that must have been a fun but long trip. I used to drive through Arizona a lot, the scenery there is much more boring. I'm glad you had a great trip!
