Yes, you'll find waves all day long every day that you wish you could drop in. But will the group want to wait around and watch you surf all day??? I think a JK fun is about the perfect boat for that run. But you kind a need to be playing get ahead of the group and catch up all day that time of year. There is a lot of slack below sfs and flows should be low and days will be short and nights will be long and river miles will be harder to atain in light. So, you will be working with 13 hours of light in the bottom of a canyon (2 of those hours are dawn and dusk). It will get cold and you wont be dry if your surfing a lot...
I saw someone do it on youtube.
