Have never run the Lewis but do have maps of the launches. Any advice - warnings from any of you Lewis vet's about bad spots or is is pretty straight foreward? Thanks

It's a pretty straight forward river. As long as it's running above 2500 cfs you'll have no worries no matter the size of the boat. You can access river levels by calling 1-800-547-1501. The only funny spot is when the river runs lower than 1800 cfs and that's at the base of the happa islands on the north side.
