Speaking about the Mets' 21st century field of dreams on Thursday, Fred Wilpon struggled to maintain his composure, his voice cracking with emotion. As the Mets unveiled their digital visions for tomorrow, releasing images of a new ballpark, Wilpon was thinking not of the computer-generated plans for the striking open-air, baseball-only facility or its modern-day amenities. Wilpon's thoughts had drifted back to his own personal field of dreams, Brooklyn's Ebbets Field. Suddenly, Wilpon could see himself at eight years old, holding his father's hand and walking through the elaborate rotunda, embracing an afternoon in the sun to watch his beloved team. "It chokes me up every time I look at the plans," Wilpon admitted.
