On September 3, 1977, the Grateful Dead performed for a crowd of 107,019 at Raceway Park, becoming the largest ticketed concert in the United States to date. The concert was the largest in the state's history. In 2017, Rolling Stone named the Raceway Park concert as part of the tour listed as one of the greatest of all time. The concert is celebrated and remembered fondly by band members and music enthusiasts alike. "I grew up in Englishtown, New Jersey, and as a child played in the green field where the concert took place. It was a blessing to join some 150,000 colorful people who attended the memorable show that summer day," said Jerry Garcia's wife, Manasha Garcia, president and co-founder of the Jerry Garcia Foundation.
