So upon arrival in CA in 66 at the age of seven, my older brothers and I immediately took to the hills, roaming the hills n mountains locally, killing rattle snakes, and following oak lined creek beds, and of course, coming into contact with poison oak groundcover beneath the coastal live oak trees.
Unlike a few of my brothers, I was able to wade through the PO with no adverse affects right from the get go, and continue to be immune to its affects to this day at age 57.
However I've known a few fellow friends n arborists whose immunity wore off as they aged, and must now avoid PO like the plague, like most of the general population does.
So an old client of mine rings me up, asks me to come up to the Julian mountains and fell a few SOD kill oaks, and cut it into firewood, to feed his woodfired pizza restaurant.
But the fates were unkind to my client a few days ago, as inspection of the first tree revealed a huge bee hive in its base, scratch 3-4 cords of wood, with the second tree having a nesting wraptor nest in it, complete with fledglings, scratch another 4-5 cords of firewood!
A bit desperate for firewood, my client points out a very old kill with lots of fallen deadwood of good size, overgrown in a field of PO. I assured my client I could winch enough wood out of there to generat a few cords atleast. While cutting paths through the PO to attach my chokers, I kept telling myself to keep my exposure levels to a minimum, but the temps were high, I was sweating profusely, and PO sawdust soon covered me pretty thoroughly.
I succeeded in getting a couple cords out n cut up on Monday, and despite practically swimming in the PO that day, my immunity held, but my client did not fair so well, in that I only generated enough wood to fire his ovens for a week or two.
I'm curious as to how many others in this biz have immunity to PO or PI, and whether they too have lost that immunity with age like some of my friends?
The triple leafed villain!
