Few yards have it here in town, but its very common in the countryside and rural properties.
I even made a web page about it - ours is poison-oak, same basic ordeal.
One that looked dramatic, was a 4" to 5" diameter trunked poison-oak vine growing up a redwood tree near the coast. At least 150 feet up into the tree.
One of its few redeeming qualities is the red fall color.
It grows in many parts of Oregon, but not "all over the place". It's thicker here is southern Oregon.
The trail in my signature, seemed to be lined 30% of the first 3/4 mile, with poison-oak. In one part of the video, I show a clip of a section that looks like ground cover.
