You may think "Hey this isn't a whitewater event"... well hey yourself, if you don't bust ass into the Pass before the current starts up, you gonna have all the whitewater you can handle.
Git your long boat out, sign up and be a real athlete --- 5 miles out-and-back through Deception Pass, with the race starting 15 minutes before slack high tide so you've got to hurry and beat the current, make the far turn and ride the big push back to the starting line. Ten sponsors have already stepped up, including major prizes from Werner, Kokatat, and Jackson.
If you don't want to race, then hang out and party at Bowman Bay campground the night before... and sign up to volunteer as a safety boater, timer, or BBQ chef.
