Anecdotal, no cite, as I just now saw it on my local (OKC, OK) news.
A Tecumseh, OK man was cleaning his garage/shed when he felt a pain in his ankle. He reached down and was bitten (again) in the hand by a pygmy rattlesnake. He falls over backward onto an old barrel where a copperhead bites him.
He is currently in the county hospital and is expected to be fine.
Damn, what a great way to get out of cleaning a messy garage! (jk, I’m glad he’s okay)
