Those look like fun rides! I was coming from Seaside up Lewis & Clark to Young's River and so to 202 south to Vernonia. The couple I met at the top of L&C were headed to Astoria. We put our heads together about the place where Logan Rd. branches off from L&C, but isn't marked in any way. I guessed it was the right road for me and turned out to have been correct (lucky!). They continued up L&C north to Astoria. I'm sure they made it fine.
