Our summers are humid, muggy and sweltering hot. Its unbearable without air conditioning. We have lightening, and lots of it. It rains on one side of the street, while the sun is shining on the other side of the street. We have bugs and lizards. We have exotic wildlife, alligators, sharks, jellyfish, snakes, big big cats, spiders and cockroaches so big they fly... Winters here the weather is simply beautiful!
