Somebody was saying they got poison oak in Texas, and that triggered a memory, so I looked it up. Poison oak is only found west of the Rocky Mountains. To quote Wikipedia (http://en.wikipedia.org/wiki/Toxicodendron_radicans) "Poison ivy grows throughout much of North America, including the Canadian Maritime provinces, Quebec, Ontario, Manitoba, and all U.S. states east of the Rocky Mountains, as well as in the mountainous areas of Mexico up to around 1,500 m (4,900 ft).
So what we have around here is good old-fashioned poison ivy. The effect of poison oak are the same however, since it is a sister species in the same genus. So it may be a moot point. But the biologist in me is a stickler for the accuracy of species ranges. Jim
