I didn't mention the trees and brush because I have no idea if they were there 60+ years ago. It was after Bonneville and the railroad were built, so the land structures should be the same, but no guess on the hillside vegetation.I was raised in the Columbia Gorge across from this site on the Washington side. I agree! If someone accidentally drove off the road in this location, you would go through an area with trees and thick brush. Then, you would hit the railroad tracks. Then, you would have to continue down the bank on the other side of the tracks, with more trees and brush!!
(And "Hi!" sorta neighbor! I almost moved to Stevenson/North Bonneville a couple times... I lived most of my life in the HR/WS area.)
