Here's my rattlesnake story: Age 19, camping in the high desert east of San Diego. We had gotten up way before dawn and went for a long hike, returning about 2pm.
Upon returning to camp, I sat in a chaise lounge chair and fell asleep.
Suddenly I was roused from a deep sleep by a stick poking my right shoulder and the voice of my youngest brother saying "don't move a muscle, there's a rattlesnake next to your right hand!"
I looked over to see that my right arm was hanging off the chair, and indeed there was a coiled rattlesnake only about 6 inches from it.
Now I find snakes fascination and don't mind them if I am out of striking range and fully awake, but this wasn't the case. I froze, and am sure that if my heart were a transmission, I stripped most of the gears.
Again I heard my brother, "don't move yet, but get ready to roll over to your left...I'll count to three....OK, one, two, three...ROLL!!!
I tumbled like I had been tossed off a bull at the rodeo. Still in a daze, I looked up to see five guys laughing their butts off. I looked over at the snake, still coiled. I pushed it with my walking stick, and it fell over. Then they laughed even louder.
When I was asleep, one of them found a rattlesnake in camp that wouldn't leave, so they used a shovel to chop off its head. (We don't like to kill them because they are part of the environment.). Then, they coiled it on the ground next to my hand, pushing the head through the coils as to hide that it had been cut off. Then, the woke me up.
So glad I was a young guy, that could have given me a heart attack!
