I've lived in Florida for 21 years now and I've seen a LOT of wildlife. Every kind of bird, armadillos, bears, raccoons, alligators and more. I've seen a number of snakes.
Sure, people have told me about seeing poisonous snakes in Florida. I've seen a few baby rattlesnakes that were not very threatening.
But I ran into a rattlesnake in my backyard not too long ago that really got my attention. This one was a good 4 foot long and could have easily killed a person.
