Lewis & Clark by Nick Bertozzi. Its a graphic novel about the preperation to the trip across the continent by L&C along with the Corps of Discovery. Its actually quite well done, although the author takes some liberties with the historical record.
Yeah, the radioactive spider bit seems too hack to me.
I am trying to read during the school year (which is not easy for me to find time for ). Little passages of a 500+ pager at a time right now.
