I lived in Coalinga as a boy in the early 70's. One day while out with my dad, his friend and our dog while they were hunting, the dog ran past me on a thin dirt dike and I actually fell down into an area where several rattlesnakes had holes. Dad and buddy had to pop a few with their shotguns to keep the snakes away and rescue me.

I personally don't remember the experience but there were snakes in Coalinga. No doubt.
