I definitely have it. I grew up with tons of copperheads. They aren’t aggressive but they are masters of camouflage and the babies are deadly venomous. Being able to spot the brown orange danger noodles smaller then my finger in the leaves I’m raking or tree I’m about to lean on has saves me a lot. Now that I’ve moved to NZ that has no snakes I still feel my snake alarm go off with an unexpected stop midstride, but it’s typically just a skink.
