I lived in Greece for four years many decades ago. I'd like to find an old friend. His name was Costa Tzamouranis. He was originally from Akovitika (near Kalamata). He would be --- now -- 73. He was a Tourist Policeman, stationed at that time in Athens and Spetsai (Spetses). He had a brother Dimitri and a sister (I forget her name).

My email is barbaracjohnson@verizon.net.
