Big South - log underwater in last drop got me
Most people take out a few eddies above the log jam on Big South and walk up to the trail. You should do that.
I decided to go to the eddy that is immediately above the log jam, to the right, about 15 or 20 feet above the huge log. There is an innocuous looking 3 ft. drop that leads into the eddy. Kent successfully boofed the drop and I followed, no boof, went deep, and got stuffed under a log that is in that drop. It is totally invisible. I surfaced with my neck and head above water and a log in my lap. It took well over a minute to get out of my boat and it was difficult to say the least. At the end my foot was caught in my backband and I was getting tired. It sucked bad but I got out. We were able to Z-drag my boat out of there and found my paddle in the log jam. I feel very fortunate to not only be living but to have all my shit so I can go paddle some class V next weekend (not).
One thing that helped me was full float bags in the stern. I think it helped keep the back end up a bit and my head out of the water. I am using a kid's scooby doo punching bag because it holds air all day, unlike any kayaking float bag I've ever bought.
Don't do that last drop. The log is still in there.
