When we arrived, some of the advance party was already coming back south, I believe due to many snags around the north side and the Kini river? I've never been to that side before, but it turned out ok, except for a bit of location confusion. A posting on cgoamn may have helped some folks? Might not have this issue again? I have a thought involving a low power FM signal that could provide announcements, but some folks may not have radios?
