I've never seen poison oak anywhere in so. Idaho. We do have poison ivy, usually at lower elevations. I live at about 4k and we have lots of it along waterways. It's easy to see and avoid, though, and I seldom hear of people getting into it.
Years ago, though, my boss's wife was a cub scout leader. She took her cubs on a hike and one of the boys slipped off into the greenery for a nature call. He wiped his butt with poison ivy and he was one hurting little kid. They had him in the hospital for a while.
