Pretty sure poison oak can be found in the eastern US, too.

I forgot to mention an apocryphal story regarding my East Texas
cousins who were Piney Woods squirrel hunters in their youth and
often came home with poison ivy lesions. My aunt used an old
procedure that involved my cousins taking a certain number (which I
don't remember) of ripe poison ivy seeds by mouth for several
(again, I don't remember how many) days. They were, reportedly,
cured of their sensitivity to poison ivy--or, at least, it was
greatly diminished.

Poison-ivy and Karst
How cave related can you get?? (I'll do everything I can to get
this site back on track)
I grew up in New York and was terribly allergic to poison ivy as a
youngster. Like, someone burned some brush with the vines in the
pile, a half-mile away. Good Lord, was I ever in an awful itchy
situation after the smoke passed over me ------. Fortunately my
lungs did not react.
When I started to do karst and geological things in upstate NY, I
discovered two things:
1. To see the bedrock I had to crawl on my belly like a snake up stream beds.
2. I could map the limestone without ever seeing it, just by mapping
where the lush poison ivy grew. (THAT is the Karst tie-in)
After I came West, I could more easily see Rocks and I gradually
lost my extreme reaction. But I learned what George
cautioned: Immunity is lost by repeated exposure.
Then I moved to Texas and discovered Poison Oak. It makes TREES
going up the cliffs with trunks as big around as Bob Oakley's thighs
around springs in the Big Bend. ESPECIALLY in what is now Big Bend
Ranch State Park.
