Yeah, leave them alone, especially rattlesnakes as they are legally protected in the TN/NC mountains where I go backpacking. I put snake killers up there with clearcut loggers and howling camp drunks who build giant bonfires.
I just got back from a 19 day backpacking trip into the Citico wilderness and saw two fine timber rattlers on two separate trails. One was named Jimmy and I sat with him for an hour and we talked. He told me he's proud of his rattle and told me he thinks he's King of the Citico and I told him he certainly is king.
I will post this trip report here as soon as I download the pics.
Rattlesnakes are like grizzlies and black bears and are the symbols of wilderness. They keep you humble and observant and respectful. NEVER kill any snake when in their territory. Karma will get you snake bit on your next trip.
If you're overly paranoid and want to hike thru the hottest summer months, invest in a pair of these snake gaiters---Turtleskins. Not cheap but only 6oz each.
