Yup!
Old timers called our bluff Rattlesnake ridge. We’ve had them in our garden and driveway usually in August. I flattened one by the garage and another lit up about 10’ behind me in the wife’s flower bed. Almost needed a change of underwear.
A snake fancier told me once that there’s a den every 3-4 miles on the bluffs up and down the River on both sides.
