(MONEY Magazine) – I want to tell you how very much I enjoyed the October Editor's Notes, ''An American Dream.'' I've recommended it to everyone I know. I've had similar stories told to me by my late father. He came from Poland. His adventures of getting to America could fill a book. True or not, I believed every one of the tales. I'm filled with warmth, but also sadness, thinking about him and the memories of those stories. Unlike you, I cannot go back to the source and meet my relatives, as every one of his nine siblings and their families were killed in concentration camps in Poland. Frances Taub Flushing, N.Y.
