Jon: MSP to CDG to VIE

I'm a little envious.  Jon, my traveling son, leaves today for two weeks in Austria, flying from here to Vienna, changing planes at Charles De Gaulle airport in Paris.  He and Chris will be spending time there in Vienna and five days in Salzburg and day trips all over the country and maybe over the border into Slovakia and/or Germany.  Jon  and I (and Jerry and Tom) spent several days in Salzburg in 2000, but the rest of Austria will be new for him.  Jon researches the heck out of a place before he travels, so by the time he gets back, he might know Austria better than some Austrians do -- except for his very limited knowledge of the German language, of course.  Have a great trip, Jon.  Keep us all posted on your whereabouts.
