Dont ride my RN then, you will want to go out and spend money.....We did the state park out there a couple years ago, it was flat as the lake. Dblock lives out on the Island way south almost to the end, the thing about the river is the variety of the ride. We go from flat cruizing to mud sliding, then out by Priest point to hit the rollers or Jetty Island to fly off the passing big boat traffic. Main thing is make certain your ski is RELIABLE....bring a few basic tools and spare spark plugs, make sure your legal as we can get stopped but rarely do. Tow line is good...been there, one of the guys from Bellingham comes down and rides his 550 with us. Its possible to go up to Snohomish and farther, only limited by fuel and the Tide, gotta watch that or you can be stranded until it returns, and then there is the Taco shack on the reservation when the tide is up!
