Good Lord!...Theres like only 3 people killed in this Country every year by rattlesnakes! Most were in Church at the time, winging them around like a News Year Eve Chinese Chattertoy! Dont blame Rattlesnakes for that!
So if you were a water Gold Hunter, you would be saying, "Hey, What shark mesh waders do y'all recommend?" "I live in Iowa, but still, I dont want to be gobbled up by a Bullshark!" That would make a lot more sense than your fear of rattlesnakes!
Or a guy Hunting up in Canada? "Hey, I want to know what aftershave or cologne to avoid wearing in Bigfoot Country, so as not to get my coal chute accidentally reamed by a Rocky mountain skunk ape, or attract the unwanted advances of a Polar Bear, or get royally rammed in the rumpus by a Narwhal? Or get my clam slammed damnably by a pack of Hangry Walruses
In fact, depending upon who you ask, most Rattlesnakes are more ascared than us than we are of them..like I said, depending on who you ask..the Snake or the Human!
I agree on your initial concept, "this is a Dangerous Planet for Humans, a guy has got to hear what might be sneaking up on him".......snakes are the least of our worries though...A guy I know up here got killed by a mosquito bite, another from a tick bite, another got killed by hitting a deer on his way to work, another got shot dead by his Wife...so hey, lets put this all in perspective!
Nobody ever got killed by hitting a rattlesnake on their way to work that I know of, so the safest thing for you to do would be quit going to church...if rattlesnakes are your Primary Death concern... !
I wear headphones alla the damned time...mainly to block out the dangerous World sounds and find a bit of peace while I hunt for pulltabs and pennies...Also, this may help you...It seems Bigfoots intent on buggering Metal detectorists prefer "Pernaud Clubman" Aftershave over Olde Spice or Axe....its available at Walgreens in case you would ever like to meet a Bigfoot...
I dont know what the hell scent Rattlesnakes prefer? Maybe something that smells like a mouse? Something from Disney World? Or the deli Counter discount section?
Cant help you here...I got Narwhal, Bullsharks and Polar bears and deer to be worrying about...and of course the Wife, who likes that 'Pernaud Clubman'..Even though I am at great risk to the Buggering Bigfoots, it gentles her up I have found, and I'm more ascared of Her than I am of them!....
