Oh jeez... don't even GO there.

I have never had it myself, but shortly after we moved into this house (June), my hubby was pulling vines off of the evergreens that block the view of our house from the road and he was completely unaware it was poison ivy! He got a mild case of it, but thought it was from some stuff in the back yard... didn't realize where he got it from... so, a few weeks later, the man goes back to pulling vines, STILL unaware. Shortly after that, he slowly developed the rash.... within a week, he woke up with his eyes nearly swelled shut. He had to go get a shot as well, it cleared up within two days after the shot.
