Lewis and Clark expedition

This not being my first time learning about Lewis and Clark, I don't know quite what to write about.  I think their friendship was a crucial factor in the success of their expedition.  Them knowing what they were doing or knowing ehat to do in a hairy situation made their journey a success.  I also think since they were the first white people the Indians saw, they did not know what to think of them. Because of this, most of them did no act hostile.  They were more in wonderment of maybe even had some confusion going on. Maybe they were thinking what a white man is doing this far West?  But having the Indians help them out by giving them horses, provisons, and advise, kept them alive and helped them complete their journey.
