Finally, I will once again recall memories of my boyhood life in those Baraboo, Wisconsin glacially-formed bluffs, a time when a pal and I caught rattlesnakes for a local reptile farm. On one occasion when I was concentrating my attention on one particular timber rattler, I inadvertently stepped over another that very fortunately wasn’t paying attention. I learned from that experience that it’s much safer when they are all coiled tightly together in a den where you can keep your eyes on most all of them at one time. RealClimate is such a place, and affords the same benefit. Thank you for that service.
