Um, this is very after-the-fact, but I went to Sisters in 2011. It was really great, except for taking 1.5 hours to make the 25 minute drive from PIL's house in Bend, and after moving the last 1/2 mile in 40 minutes giving up on the car and parking at the side of the road south of town and hoofing it the rest of the way in. If I go again, I'll take a friend who wants to see the show too, and get a hotel room in town and not try to drive anywhere during the show! Leave the DH at his parents house if he wants to help me drive to Oregon, I'd still get a hotel in Sisters for myself. Minimum 2 night stay during that weekend, I think?
