From portland, take 26w, take the (6) Banks exit (right after north plains) to 47..
go right towards hillsboro a few miles and then take any road towards the winerys.
8-10 miles of sharp turns with swoops thrown in. explore the area and get addicted!
there are GOOD dirt roads to get sideways on (can hit many going 50+)
You can really get lost for a little while and really have fun, no two drives have to be the same if you dont want em.
tips: have a caller ahead on some of the dirts just in case
I havent seen a single PO in the 4 months playing back there.
