Advocating for the Preservation of Desert Wildlands
Great photos - looks like it to me. They don't always warn. See these in the yard sometimes; while mountain biking, one was resting in the shade...glad I went into a tricky place and had to walk my bike through that time, or I would have been going faster and maybe struck by that diamondback! (at least their venom is not as bad as that of Mojave rattlers, or so I've heard)
When I was about 13 back home in the piney woods of south Georgia, while exploring a section of those woods I heard a loud rattle very close- I froze still, did not move, didn't even move my head to look- and after what seemed like a lifetime the buzzing sound went away, and I came out of my frozen state and lit out for the dirt road.I have experienced nothing like that since, and hope to never irritate another rattlesnake in my lifetime. Being about 2 miles via dirt road walking from my house, I would never have survived a bite from what probably was a very large, eastern diamondback.
