No shiit, brother?! You do have some pretty primo ground for snakes, though - all the rocks, veg, etc. Might be time for me to gift you some 9mm snakeshot.
I hate the rattlers here, we have a couple types. Western Diamondback, and the Mojave. That Mojave is a mean motherfucker, and will sit in trees. They're quiet, and may or may not rattle, before they try to fuk you up. Gotta keep your eyes open when you're in al area with head-high branches.
This guy right here I stumbled upon last summer - he was just getting his meal, and I left him alone. He hit a big bird, and was chowing down. He was impressive, and THICK.
