What is Austria?

     This one’s pretty straightforward: As requested, more information on a quadruple-stumper from Thursday, 2-10: In The Country That Borders…: “Liechtenstein and Slovakia.” (Strangely, the request, my first use of “quadruple-stumper,” and the clue itself all came from the same entry on the 10th.)
     All I need to do to show why this is correct is to show a map of Europe.  But why is it so hard to remember such things while I’m playing at home?  I hope blog entries like this will help.  Heaven knows I need to look at more maps to study for the show.

     As Slovakia and Liechtenstein are on opposite sides of the country, Austria is obviously the only possible correct response.
