Glad you enjoyed halbie. Hopefully you got the chance to grab a bite at Mazama (well made sandwiches & great setting), or in Winthrop with multiple good restaurants.
I hope you caught hwy 20 during low traffic volume as it can get quite backed up. We have done the hwy 20/hwy 2 loop for 500 plus mile days. I don't know if the RS has a good enough seat for that! It can be quite the gear jammin' day.
