I know this is a long shot, but I had a pen pal from Turku in the 1970's. I was put in contact with him through a television show in the U.S. called The Big Blue Marble. I can not remember his name. All I remember is that he had a little brother and both of them had the blondest of hair, which I am sure is not uncommon. I was living in Oregon, USA at the time. What is the population of Turku? Is it so large that I would have no chance of finding my old pen pal?
