Thanks for posting the pics. Looks fun, I can't wait for my upcoming trip.
I don't mean to be nit-picky here and am just wondering so a few friendly quesitons about how you're rigged...I noticed that on triplet you didn't have anything for the kids to hold onto...have you considered some straps across the paco pads? Sure looks like they could end up swimming pretty easy.
At HH mile it does look like you have a bowline or something for them to hold onto...but I'm wondering how long that rope is...is it long enough that it could wrap around their feet?
Lastly, dude in the front with the paddle seemed to cause you more harm than good.
Thanks for the hike suggestion. We are planning on heading up to the falls. did you check out the cave or petroglyphs/pictographs?
