When two explorers hook up, it makes for a relationship that's never boring. Leo and Sagittarius both love social events, sports and adventures of all types. Sagittarius will open Leo's eyes to the world around them, and Leo will never tire of hearing Sagittarius speak passionately about saving the world. This is a relationship full of optimism, playfulness and passion. It may not have long-term potential, though, because both Leo and Sagittarius tend to live in the moment and aren't terribly concerned with building a solid foundation for the future. But it will be fun while it lasts.
