Making a run down to Oregon next Friday (28th) to pick up some brass and primers and will be in the Stayton area with some time to kill between pick-ups. I've camped at Silver Falls a few times but if someone local has some favorite roads in that area they wouldn't mind showing off.
Looks like with 2 meetings at a Pro Build off of I-205 exit 12A one between 9 and 10 a.m. and the other at 3:30 p.m. I might be better off to try a loop up the Columbia River. I'm thinking East bound on the Oregon Side, cross a bridge and return Westbound on the WA side with maybe a stop for food so that I land back the Pro Build around 3:30
