Along Willamette Falls Drive on the river side of the road, between the Sunset cut off & the Willamette area. There are groves of them! Some shorter ones by the old recycling center were sprayed, but are still alive. Taller ones are growing in a wooded area before that, as you head to Willamette. I live on Sunset hill & have destroyed at least 6 quickly growing seedlings in the past few years.
