I went to the 2011 race which was fun.
Friday was the kayak race with prizes.
12 miles downriver, they cleared the river of speedboats. No rapids but some eddies. Nice event.
Sat was the tubing. We tied a couple tubes together, filled the camelbak with Rum punch and floated the same course watching the floats and such.
again, great time.
The 2012 event is 10-12 August so I am planning to attend that one too.
