There are actually a few things going on in Cda during July. The Dukes of Hauser Freeride contest is July 12 and July 13 there is a demo day with different board companies and boats to ride behind. Then July 26 is the ButterStomp Comp in Ione. All these events are super fun. If you get out to any of them, please come say hello. Check the events page at http://www.wakefirst.com
for more info.
Also the guys up at Hayden Board School at the Hayden Lake Marina regularly take people out. Give them a call at 509-590-5850.
