The young snakes are the ones you really need to be careful of. They pump all their venom into a bite- unable to regulate venom amounts. Older snakes realize human is not worth wasting venom and will often dry bite. Either way- not worth messing with. Gives you a sense of humility being out in country where shit could go wrong in a hurry.
An old timer told me this many many years ago. He swore a little one is way more dangerous than the big ones on account of this.
More of a chance to be bitten is when they are shedding their skin as their eyes get blurred and they strike at anything.
When you are in an area where there are buzz worms (as we call them) and cattle keep an eye out for the cattle as every once in awhile you will see a cow or more than likely the calf with a huge swelled up nose. They got too curious of the buzz worm and stuck their nose where it shouldn't have been.
I can't hear their rattle anymore so i always tell my bride if she hears one to be sure to let me know right away. I guess it is the tone of the rattle according to my hearing Doctor, that is why i can no longer hear it.
Another old tale is they always rattle before biting. BS on that one.
Same thing with an animal won't eat or drink if they have rabies. That is BS too as found out the hard way. Have to be careful now not to get bit by an animal as on the last shot that i received i became allergic to the darn antidote. I asked the Doc what happens if i would get bit again by a rabid animal and he calmly said, " you are going to die".
True story!
