This year is the 40th anniversary of a Thanksgiving reunion unlike any other. Erich and Karl Bley were born and raised in East Germany, but separated when the iron curtain was lowered. Erich, the older brother, escaped with his fiancé. The reunion includes coded letters and a bold, daring escape. Also: Not all family traditions involve togetherness. Patrick and Kim Sauer have spent the last twenty years making sure they are NOT together at the holidays.
