The runnable range is a wild SWAG and should be used with caution. If you run this, please add a comment or report, so that we can develop a correlation.
After some warm up rapids, you come to log cabin rapids. There is a ledge at the top, that has a surf wave on river left. At the bottom underneath the bridge, there is a 3 foot ledge with a ugly hole. Run this left, or extreme right.
