In St. Joseph, MO, we visited the Pony Express Museum. Again, the camera wasn't working properly, so unfortunately I don't have photos.
This museum was wonderful! It had a great handout that you carried with you that explained some things and told you special things to look for. We all enjoyed moving the mochilas (mail bags) from one pony to the next. You were supposed to time yourself.
Alexandra loved the play area where she got to dress up and play like she was a pioneer lady. They had a neat, handmade wooden kitchen area & some pretend food, etc.
Altogether, we spent about 2 hours here. I highly recommend it. (Photo is of 2 postcards and Alexandra's Pony Express horse, Brownie.)
