It began in 2009 with Citi Field, home of the New York Mets. When the stadium opened, Shake Shack was there, and it instantly became a huge hit. In 2011, Shake Shack traveled down I-95 to Nationals Park in Washington, D.C. where, despite its New York origins, the Shackburger and Nats fans have become fast friends. Latest word is that, when the Atlanta Braves open in the new SunTrust Park in 2017, Shake Shack will be there for the first pitch. At least, that’s what they’re hoping for, as the two parties are still in negotiations. All that’s left in the National League East would be Philadelphia and Miami. There are already Shake Shacks in both cities but our money is on Marlins Park, as Citizens Bank Park just added Wayback Burgers this year.
