[Az-Geocaching] Poison Oak/Ivy

[Brian Cluff]

This description helped a ton.  At least it lets me know that the immune
system doesn't work backwards on certain things.  It sounds in the case of
poison ivy/owk that it's actually better to NOT have much of an immunity.

Crossing my fingers that I never run into the stuff.... luckily it doesn't
grow very well in the desert
