Kinda confused as to where you want to go on the Coast, but Hwy 34 going to Waldport is an amazing ride. Hardly any traffic, and sweeping turns, just about perfect at 50-55 mph. Hwy 36 to Reedsport is another awesome ride. More traffic than 34, but faster. There is an Elk Viewing Area along the way just before you get into town in Reedsport, that is really cool. A large herd hangs out there most of the time. ANY road you choose in the northern part of the state is going to have way more traffic on it. This weekend is the Rhodenderon Festival in Florence, so every State Trooper will be hanging out on the 101. Watch your speed!!
