Thanks for the report and pics. I have someone who has tried to arrange a hike (with me and wife) on the Jacks River. Maybe some day. Good to see what it's like, though.
And I agree with you about fording streams with boots on. As the TV commercial used to say "Just Do It!"
I also like reading your comments on your AARN pack. I like front pockets for camera and some food to much on, plus maps and guides, maybe a place for a rain hat, etc.
And how come the one feller is wearing a head lamp in the middle of the day? Seems like a good way to lose it, if he stumbled in a stream crossing.
