Thanks for pointing that one out. I finally downloaded that to my eReader today, but I read a bit of it a few weeks ago and the beginning had me convinced it should be a fun read.
While I was poking around I found the Journals of Lewis and Clark too. I've read an edited versions of them, and I'm not sure if this is or not, but I am looking forward to reading them again. It's been a long time and I really enjoyed it the first time.
