Oh, and if you see this, run away very, very fast!
A Trip Down PI Lane

We have had good luck with Ivy Dry at our house.  My son used to be on the boat crew at Erie Canal Village and the tow rope gets dragged through the poison ivy along the bank and he was constantly getting the dreaded rash.

I've actually done pretty well this summer (compared to last year.)  The worst case I've had (and really the only bad case this year) came from putting on a friend's gloves to avoid getting it, but clearly, they were already covered with it, since I got it on both hands, and only one went near the stuff.  When I cache in my own geomobile, I carry rubbing alcohol (cheap compared to all the other stuff like ivy block and Technu) and rub it in really well.  Of course, knowing what to look for and then not touching it, is even better, but I usually can just walk by and get a rash.

Another contributing factor to missing PI is if you are hunting a FTF.  I'm not completely sure of the scientific reason behind this, but vision becomes hyper focused looking for plastic and metal and not flora and fauna.

The affected area heals faster if you have the will power to refrain from digging at it. The more you scratch it,  the more it itches and this turns into a vicious cycle. I have had it so many times I can identify that initial sign of itching before any visual symptoms appear. Some of you may have heard that the liquid from the blisters won't promote new areas of rash and only areas of skin that were exposed to the plant will become affected. This is not true for people who are highly allergic to PI. I'm living proof that the liquid will start new areas of rash.
  Some highly sensitive people may develop blisters on their lips and inside their mouths from eating cashew nuts. This is due to contamination of the nuts by the urushiol oil that is found on the outside of the raw cashew pods. This oil transfer happens occasionally during the processing of the nuts.
