Location.  I live in the south.  While I am okay with relocating anywhere within the U.S….I would prefer to find someone close to where I live.  I think this is important in getting to know a person.  A match from the west coast will be a lot harder to stay in touch and meet up with.  However a match who lives in the South or even the east coast will be a lot easier to meet up with and stay in touch.  However I would still be open to anyone within the U.S. no matter where they live.
