Wow. I hope you have a great trip. This is my very favorite time of year to be in the canyon. Silvers, half-pounders, and steelhead. If you've never been down this section before you should follow a person that you trust.
Thanks... I've been down it a couple of times but never rowed it. I'm headed down with a couple of VERY experienced guys - we've had a couple of "planning sessions" and have been looking at a lot aerial photo's of some of the nastier runs.
It sounds like you are in good hands. Use this sites email feature on the top to shoot Aaron H. a note. He's likely still on the river a ton until you trip but might have a minute to warn you on a couple of "gotchas" .
