After seven years or so of digging through stacks of mesquite, I finally met a scorpion that was smarter than me. ...it stayed on the bottom of the board where I couldn't see it. Never did see it, actually. I was tossing the board away and saying very bad things almost before the hurt started. It's now nearly five hours later and the 'burn like fire' has subsided somewhat. Burned like hell for every bit of three hours.
Be careful out there.
