Fred Wells Tennis Center at Fort Snelling in Minnesota has two air-supported domes covering their tennis courts to provide players the ability to practice and play even with a foot – or more! – of snow on the ground. To keep everyone warm at all times, the domes are linked by an enclosed walkway with additional amenities. Fred Wells Tennis Center was so pleased with the increased use provided by the domes that they requested to reconfigure one of their existing domes to add a court – and 5,400 hours of year-round playing time along with it.
