Really interesting, Jim. I googled North American Brown Cobra and guess what I got? Picture of a really nice looking Shelby muscle car . . .
Yes, luckily for us in Florida there is enough swampy land and infertile land around that lots of "green space" is left for the critters. Most of the human development is near the coastline. There's also a lot of pasture land in Florida - did you know that we are the second biggest cattle producing state in the US after Texas?
We also have "corrections" by Mother Nature in the form of hurricanes once in a while. Ma just comes along with a sweep of her hand and destroys whole areas of housing that are in her way. Silly humans build houses too near the coastline, or on land that is too close to sea level, or in flood plains . . swoosshh, back they go to their "natural" state in one day.
