I live in north Florida where winters are mild by most standards but we do get down to 18-19 degrees overnight at times. I usually wrap our outside faucets in an old sock and/or part of a tshirt then put one of those caps that you get at Lowes/Home Depot. Pretty good luck...no frozen pipes ever. I have one neighbor who tells me that my method isn't enough and I've just been lucky. My other neighbor (used to live in Minnesota) laughs and says that my way is actually overkill for down here. Just wondering what you guys think?
