Yes, yes, I know! The natural world is filled with perils for us humans. Not only snakes but scorpions, tarantulas and other spiders, mosquitoes, (We're in the midst of a West Nile Virus "epidemic" here.) bees, (Yes, bees have a venom that is poisonous.) wasps, Blister Beetles, Puss Caterpillars (aka Asp Caterpillars) centipedes, the Gaff Top Sail Catfish, sting rays, Portuguese Man-O-War and that's just here in Texas.
The thing to remember is that with the exception of two creatures mentioned above (tall tales not withstanding) none aggressively seek out us with the intention of doing us harm. What are those two? The mosquito and man! As to the rest, if you leave them alone they will leave you alone. Yes, I have been bitten by a rattle snake, but it was my own stupidity, not the snake's aggressiveness that caused it. It felt threatened by my actions therefore...
Yes, there are lots of things to worry about, if we choose to, such as "Watch out for elephants in case a circus comes to town!" This particular quote comes from Daisy Duck's (Apropos for BYC I think.
) warning to Donald while she was backseat driving. (Saw it in a comic book when I was a small boy, and it stuck.
)
My point is that one shouldn't worry about such things. Just be aware of your surroundings.
