PPS - Hey, I checked on this website - http://www.ghosttowns.com/states/or/valsetz.html

It seems the Valsetz Road is private - open to the public on weekends. Can't remember if I used it on a weekend or had difficulty reading the signs that day. Of course, I would NEVER break the law. To be on the safe side you can continue down the Willamette Valley to Corvallis and cut across on Hwy 34 to Waldport - - all legal.
