its been over 30 years since I've paddled that river but I notice there is still plenty of livery competition.
which one you call or message depends on what stretch of river you want to do. Get their shuttle service rates. You'll get the best rate if you operate on livery time- warm weekends when they're putting their rental fleet on the water . Expect to pay a lot more if they end up making a special trip just for you
