Despite the heat and the humidity, south Florida has got to be, hands down, the coolest place in the country.
It has huge rattlesnakes. It has alligator and crocodiles. Florida panthers. The Everglades, the Keys, smugglers, and Cubans washing up on shore at Jimmy Buffet's house. A river named the Shark River, complete with actual sharks. The only coral reefs in the continental U.S., some of the nicest beaches in the world on the west coast, and Miami on the east.
A now it has giant pythons.
The other day I ran across a news item from the Miami Herald that included photos of a 13-foot Burmese Python that was found dead in the Everglades after killing and swallowing a 6-foot alligator. It didn't go down well. This reminded me of something I'd read a couple of years ago about an epic fight between the same two species observed by tourists on the Anghinga trail, a popular tourist spot, in front of a crowd of up to 200 people. The fight lasted at least 24 hours, and in that case, as well as other cases I've now researched, the gator came out on top.
The pythons have been introduced by people who got tired of keeping the giants as pets, and they've now become established and are breeding in the Everglades. They've become so common that park employees regularly run them over with lawnmowers.
Ecologically, of course, introduced species can wreak havoc. The only mitigating factor may be that Florida's ecosystem is such a basket case anyway. Even many of the species people think of as typically Floridian -- the banyan tree, the coconut palm, citrus and banana trees -- are actually non-native. There are also reproducing populations of several parrot and lizard species, including the green iguana. 35 fish species have become established, include common aquarium fish like the freshwater oscar and pacu and the saltwater orbiculate batfish. Then there's the fact that the Everglades as they exist now barely resemble the Everglades of 100 years ago, due to agriculture and the construction of flood-control canals and levees, and the current ambitious restoration effort is probably hopeless, for the most part.
The park rangers will attempt to irradicate the pythons. Good luck with that. I just hope all the crazies down there survive hurricane Wilma OK.

Popped python, Everglades. The snake is nearly broken in half, with its tail near the helicopter and mysteriously missing head toward the top (probably the result of another gator encounter, before or after death). The ingested gator's hindquarters and tail protrude to the bottom right.
