OH christ. That sucks. I've been scared of poison oak after reading that almost every cache around here is in or around patches of it, and i have no idea what it looks like... well, now i do. I've looked it up, and am going to be sure to bring pictures of it on my next cache so i know what to avoid. I'm used to the Poison Ivy in the South, Poison Oak is new to me, though i know we have plenty of that down there too.
