Unfortunately, @Sunshinegirl11, you’ve demonstrated a fundamental flaw in the way many people approach and assess risk. While it may be uppermost in your mind that a man was recently bitten by a rattler and died near you, why would that make that risk – a real risk, to be sure! – your biggest concern?
I’m not saying that it shouldn’t be or that it isn’t. I don’t know your hiking area or the trails or even what part of the country you’re in – and I’m not asking – but what would make rattlers (just to use your example) a bigger or more serious risk than bears (which you also brought up) or wolves, mountain lions… or predatory humans?
By all means you should be aware of the risks of the area that you hike, but don’t just be concerned (or even “most concerned”) about the one you heard of most recently, just because it’s the one being given the most air time.
In most national and state parks in the USA I think that the biggest danger to a solo hiker – and particularly so to a solo female hiker – is probably going to be “other humans”. I don’t know that for certain, but I do know that from coast to coast far, far more humans kill (or rape, or maim) other humans than the number of humans that are injured or killed from all other species of animal combined.
Don’t ignore rattlers, at all, if they’re a risk in your area. Be aware of them, have a plan to deal with them and with snakebite, if it occurs. But talk to the park rangers or administrators or other hikers to get a full picture of ALL likely risks where you plan to be. And then plan accordingly.
