I was just recently in the New York over the Memorial Day Weekend and I made a trip down to the 9/11 Memorial Site Park. This same area was once referred to as Ground Zero, after the terrorist attacks collapsed the Twin Towers. This same area is now home to an amazing 9/11 Memorial Site Park. The base outlines where the South and North towers once stood are now gigantic waterfall pools surrounded by the names of the victims from the terrorist attacks. Thousands of people visit this memorial site each day to pay their respects to all the fallen heros and victims. The new Freedom Tower is currently being built and is under construction nearing completion right beside the park. The building will reach 1776 feet tall representing the independence of the United States of America. Across the 9/11 Memorial Park there are dozens of beautiful Oak trees and very symbolic groups of 2 parallel rows of turf very much like the twin towers. The turf growing in these rows is Kentucky Bluegrass and is perfectly maintained without any weeds.
Here is a video i shot while i was visiting the Memorial park. Pretty amazing stuff.
