As we experience "the coldest first two weeks of October ever recorded," it's not hard to think of warm, sun-washed places like Santorini, which is pictured here. A student group, my wife and I spent several hours on this amazing island in the summer of 2004. As winter sets in, I long to go back. Do you want to come along?
