1. I can coexist easily and happily with my husband when we're not driving in traffic. There wasn't any except entering and departing from large cities (Seattle and Omaha).
2. There's a lot of drilling for oil and gas, and mining for minerals, in southern Wyoming. Some of it is being done by a company called Halliburton.
3. In some midwest restaurants, there's not much menu space given to fresh vegetables or healthy entrees.
4. Iowa is mostly hilly and Nebraska is mostly not. Iowa mostly doesn't need to have farmland irrigated and Nebraska mostly does. At least the parts we saw.
5. People in small towns are usually friendly and helpful, at least to us.
6. It's economical to spend the night in someone's home (via Couchsurfing.org or EvergreenClub.com), but it requires the energy and interest in conversation with newly-met people. Sometimes a motel room is easier after a long day's drive.
7. Sometimes it's a good idea to travel with a group, especially when you need a knowledgeable guide to cover an area (like the Black Hills in South Dakota).
8. Warren Buffett is an interesting rich guy and a good teacher.
9. Long days of sitting in a car or on a bus can result in lumbar strain which may require multiple trips to the chiropractor after arriving home.
10. It's wonderful to sleep again in your own bed - even if you catch a virus three days after you get back.
