We have a very healthy population of Eastern Diamondback Rattlers. But, you don't see them very often unless they are moving. They have very good camouflage and tend to set up ambush points for their prey. Even if it set up near a trail you are walking, it is going to rely on its camouflage and keep its rattle still and let the giant human go by without calling attention to its self.
Most of the rattlers will lie in the palmettos. We use caution when moving through the palmettos for that reason. I see a lot more pygmy rattlers and they just lay there. I've tapped them on the nose with an arrow and they just sit there.
This video shows why you don't see many and also a typical reaction to being messed with.

This snake was originally reported as 15'. LOL I kept telling people there wasn't no way. But, people would rather believe what they have heard and not look at facts. You google 15' or 14' rattle snake and pictures and articles will talk about this one.

I run into people all the time (my dad and brother) who will swear that they have seen 10' or 12' rattle snakes. Even after I remind them that no one has ever documented a rattler larger than 96". They say I know but...
Even with all of the herps out there and all of the rattle snake round ups. They all still say I know but... Or I know what I saw. LOL He was right there stretched across alligator alley and his tail was still in the brush and his head was off the other side striking at skunk ape. His head was nigh as big as ole skunk apes foot and that's a bigfoot! :online2long:
