We had Loretta as our guide and feel like we hit the jackpot! Engaging, knowledgeable, charismatic...she made the tour very interesting . Her knowledge and expertise, particularly regarding 9/11, was impressive. The memorial is almost indescribable - the overwhelming loss our country felt and will always continue to feel, is masterfully, impeccably and respectfully represented. The lives of the fallen, the bravery of the responders, the pain of the survivors and families and the dedication of volunteers is profoundly and beautifully displayed. It is a somber, highly emotional memorial and will take a few hours to see and experience. We will never forget.
