I suspect the rash between my fingers that isn't as bad yet hasn't completely gone away in two weeks wasn't caused by poison ivy despite similarities to it. Upon spending more time in the area where I'd been moving things in the backyard sans gloves I discovered a large number of cocoons that seem to have black hairs/spines woven into them. They look just like the spines featured on the toxic white and black fuzzy caterpillars that showed up this summer. The ones that can cause a poison-ivy like rash if contacted. I'm thinking I should wear some gloves and destroy as many of those as I can find before they open in the Spring.
