In summary
My roadtrip was fun.
Not everything went according to plan, but I made the best of things considering.
I met my mother's new husband. He is a great guy and he is wonderful to my mother. I am extremely happy that she is in a better situation than she was the last time I saw her. She actually told me that my advice and what I had said to her on my last trip is mostly responsible for where she is now in her life.
I ended up not going to Seattle, instead hitting Portland a week early. Enjoyed myself. Met a lot of new and interesting people, and saw a lot of sights.
All told, I drove 5243.8 miles in two weeks, with most of the mileage being the first two and last two days.
I have photos, but I'll have to edit them and that'll have to wait. If you'll recall, I was moving before the roadtrip, so I'm still unpacking in the new house, which itself is an adventure.
