A symbol that remembers the lives lost on September 11, 2001, and honors how our country came together after the terror attacks continues to grow in a field in New York 20 years later.

Gary and Darlene Cronk created the patriotic tribute, cutting U-S-A into their farmland days after the attacks on September 23, 2001, and it's been there ever since. The 3 letters, standing 360 feet high, take up over an acre each. The field can be seen in a clearing in Bluff Point, New York overlooking Keuka Lake.

The Cronk's sold the property to Greg MacDonald and his son who have kept the patriotic tradition going and promise to continue to do so as long as they own the land.

Photographer John Kucko features the field in his annual calendar. When he visited the field on the anniversary of the terror attacks he took a picture of the Cronk's in front of their creation to include in the 2021 edition, marking the 20th anniversary.

Kucko has raised over $20,000 with the sale of his calendars over the years with the money going toward the effort to build the Autism Nature Trail at Letchworth State Park. Calendars are $16 each plus shipping and can be ordered at Kucko Calendars on Facebook.
