Great pictures! I love driving along next to the railroad tracks and slowly overtaking the trains. Along I-10 in New Mexico and Arizona you see a lot of trains throughout the two states!
Isn't the Mississippi a big river? It's impressive every time you drive across the bridge. Interesting facts about St. Joseph. the Pony Express really was short lived, the old wild west... The genius highway was another interesting fact. I never did much research on those areas when I drove through. I'm glad you guys had a fun and safe trip!
