Hi Carol! My name is Kate - from GA - I'll be in Sofia for the second half of May. I've really enjoyed reading your blog! I came across it after finding Girl Meets Bulgaria. I spent a few weeks in Sofia in the Fall of 2007 (my fiance is Bulgarian) and am looking forward to wandering around there again. Thanks for the weather warning! My fiance's Mom warned me that I should bring boots.  No flip-flops.  
Anyway, I'd love to meet for coffee or drinks if you're available at all during that time! I'd love to hear more about your experiences.  Please shoot me an email if you have time!

Best,
Kate
