Damn Jeff! Next run duct tape the paddle to one hand. That ought to save you a few hundred bucks! Just kidding. Hope you find it. I kept an eye out for it last night as we went down, but didn't see it. Most of the time the water has your attention so its hard to check the banks for the paddle though.
One thought is to hike the banks from blackrock down. You might get lucky if it hung up on something in the first mile or so below blackrock.
Kent, I'm meeting up with Steve to run lower at 11:30 today. Maybe we'll see you up there.
