This is a relaxed event sponsored by Liquid Adventures Kayak school - http://www.liquidadventures.org. It is a lot of fun and a great introduction to slalom racing in a positive environment. see http://www.liquidadventures.org./feedercup.html . On this occasion the river level (LF gauge) was 2.5 ft which meant there was some flow but no turbulence. My wife brought her camera and took these photos.
