Hubby & I are traveling to Oregon from northern California in late September. We will be gone a little over a week and will be camping the entire trip. We would like to spend about three nights in the Yamhill Valley. Please recommend a campground in this area. We are not the cement slab, KOA types, but would like full hook-up with as much natural beauty as possible for this part of the trip. Thanks so much for your expert help!
