White roses at the 9/11 Memorial

Mark Mikulski doesn't deliver roses for a living. The deliveries he makes are purely out of love. For the last four years, Mark has gone to the 9/11 Memorial in Manhattan with a clipboard of names and a bucket of white roses. He places the roses in the names of victims of the 2001 and 1993 World Trade Center terror attacks to honor their birthdays. CORRECTION: Mikulski is an employee, not a volunteer.
