Two big rivers

I'm heading out today for a 2 week trip down the Grand Canyon, and will undoubtedly have some good tales from there; if nothing else, we are getting a prescribed flood for a day or two that it appears may reach ind us at Lava Falls, so that'll be good for some yucks.  And my buddy Rocky Contos reached the sea this week in the "First Descent of the Amazon" (you'd have thunk that had been done a hundred years ago, but apparently not so) and he's returning home with his locked-up laptop that has a tale of our river adventures together in Peru in September on his hard drive  - and Rocky's story is a good one as well - so I should have some fodder for this venue after Thanksgiving.
