April Is The Month of Rattlesnake Festivals In SWOK Only twice have I encountered them in the wild. Once walking around a mountain in the refuge, no big deal. The other was while fishing around a tall-grass pond bank. I never saw it, but the millisecond it started rattling, I popped my Crocs in reverse and went on fishing the other way around. Still, the idea of catching rattlesnakes is still somewhat odd to me. They have alarms on them to keep humans from a painful bite, so why do we continue to gather up these danger noodles? Because it's kind of neat.
