So I think we're gonna tackle the Cohos next year (2015). Truthfully, we'd like to hike in the Fall but may be too antsy to wait that long and Spring fits our schedule better. Is it too nasty to hike this in the Spring? How early is too early? Are bugs terrible in the early summer? Is it maintained well? Can this thing be done in 8-10 days for a couple of strong hikers or will route-finding prohibit that?
