The only thing(s) I may add are pretty much written up in here, other than I would plan on getting wet in the process, If I was in a SOT Kayak!
Green River Rapids
To simplify it for red creek I drop in on the left and then veer right, pretty straight forward. It would be an easy portage also but I would think you would only need to portage the drop in, if at all.....
Have fun and be safe
