Scorpion Weed: Don't Touch This

I foolishly pulled up this weed which is growing all over the place this year, and that was a mistake.

It gave me a horrible itchy blistery rash like poison ivy -- I was in urgent care on the 4th of July instead of enjoying the famous Corrales parade. Turns out this is likely the culprit for my three years of "plague" - I had no idea...this year was the worst ever.
