SunTrust Park is not just a baseball stadium. The cranes may still be up, the bridges may still be under construction, and the parking may not be fluid by the time the first pitch is thrown on the field of the Atlanta Braves’ new home field 10 miles northwest of downtown Atlanta, but don’t be fooled — the fan experience is ready to go. Among the 2.5 million square feet of field, stadium and outside-the-walls entertainment at the ballpark on Cobb Parkway in Cumberland lives the most technologically advanced ballpark in the country — it is the newest one, after all.
