Hey!
I'm up for something Saturday too! The main channel is a bit big at 5, but the middle is still fun at that level.
I've done the Rouge, but my recollection of it is so vague as to be completely useless. I would definitively only go there with someone who knows it... What I remember of the Seven Sisters (i.e. Canyon) section at lower levels, if you walk the Sisters themselves (big waterfalls), is that it's a is pool-drop-pool Class II to IV run, and the big stuff can be avoided/portaged easily. For instance, next to the Washing Machine, there's a sneak run called the Dryer. Plus the Washing Machine is a body surfing spot, once we all jumped repeatedly into it, canonball-style, so it's not such a big deal if one swims there...
Anyway, I would love to pay for gas/food/beer if someone gives me a ride, any river!
