Yes, Sacagawea was awesome; she did everything that everyone else did but with a baby on her back. And it wouldn’t be a stretch to say that they might not have made it without her. Babies must have been made of way tougher stuff 200 years ago because I can’t imagine taking an infant along with me hundreds of miles through the wilderness.
Well, daycare wasn't much of an alternative back then. ;)
Sad that we don’t seem to know for sure what happened to her.
