We are coming from Shady Cove at the end of July. Despite hours of reading, I'm still confused. I know I'm coming in at a fee station in the southwest. Better to go clockwise or counter clockwise? The whole loop is 33 miles, so I assume I'll have to doubleback somewhere since we are headed to Redmond. I know it depends on the individual, but would three hours do it for the loop? Thanks.
