HICKSVILLE - People across Long Island are finding their own ways to mark the 10th anniversary of Sept. 11 and reflect on those whose lives were lost that day.At Eisenhower Park in Nassau County, people filtered through the 9/11 memorial, leaving candles and flowers in memory of the fallen. Some visitors sat far away from the memorial, taking it in from a distance. Douglas Sapala, a father of two from Port Jefferson Station, says he wants to turn the anniversary into something positive for his children by teaching them about that moment in history.For Maria and Manuel Alvez, of Hicksville, the 10th anniversary of the attacks leaves them with mixed emotions. But they say having a replica of the Twin Towers built by a neighbor who was a first responder just steps away helps them and their community heal.
