Excellent! You better come over to the Lochsa. It won't be BIG this year, but even when it's mellow it's a superstar. Last year was epic! If I were you, I'd check out the MF Flathead, it's got some IV's and is moderate/high volume, but just a few, there is a day run and the wilderness run. Maybe the kayakers from the Beartooth area will chime in here on the Buzz, there's some kayaking runs down there, more creeky though. I've found it incredibly easy to make boating friends, both through approaching boaters and also bugging guides (that's how I got introduced to the Lochsa). You'll inevitably run into some attitudes against newbies (it can be really bad in Montana), but just keep talking and being friendly and you'll meet up with the right folks.
