Clipper Magazine Stadium is a far cry from little Stumpf Field. While Stumpf Field was a modest little ballpark that held approximately 750 people, Clipper Magazine Stadium is a baseball arena. With 10x the capacity of the original ballpark, the Barnstormers new 7,500 seat stadium is built way above Double-A standards. Every one of those 7,500 chairs is necessary as well, since the Barnstormers have sold out every ticket many times in its inaugural season.
