Very interesting. And what a great view of the river, the best that I've seen. We wanted to go last time we were out there but talking to a ranger in Jacob Lake, she said it was not passable. They had a major wash-out. So we didn't try it.
Not sure what camera you are using, the video was pretty good, if you have a separate microphone I'd suggest getting something called a 'dead cat'. No joke, they look like a fuzzy sock that slides over the mic and dampens all that wind noise. Also cut your exposure back a little. Just a couple suggestions.
Hope to make it out there this summer.
Dead CatsGeez that point and shoot version is grossly overpriced.
