That is Rattlesnake Grade near the Grand Ronde River boarding Oregon and Idaho. We most likely will plan the event for next year if we get enouh interest (check the regional forums) Our group calls themselves "Northwest Bimmers", although we have not adopted any official by-laws or dues, but we are working on it. We are looking for members! I have a photo of the grade if anyone is interested.
Congrats on the new baby BOY!
