Check out Tecnu Poison Ivy Treatment, Poison Oak Treatment from TecLabs Inc.
Great for Poison Ivy and oak. It's pricey, but having the junk get all swollen and nasty is worse.
I used to be a firefighter in So Oregon, we'd see old growth 'forests' of Oak, things with 6 inch diameter trunks, evil, evil shit. I don't get PI or PO very bad, but most people do. a COLD shower is key, the cold closes up your pores, and then you can scrub oil off w/ dish soap. Bleach, Gas, etc... is pretty bad for your skin as it absorbs, but is effective. I don't recommend it, especially on the southern real estate. it doesnt really remove the oils, but dries out you skin so they don't absorb.
The Tecnu wont get rid of it entirely, but works very well.
Why don't you folks boof of the top South Chasm Wall with a parachute, much more sporting.
