Most likely you don’t have a kid-sized stadium already built in your backyard. But if you build it, they will come. Or just buy and blow up an Inflatable Backyard Sports Arena. Boom roasted. It only takes 2 minutes to inflate this 15′ by 10′ rip resistant PVC shell into a bouncy backyard field of dreams ready to play football, volleyball, soccer, or basketball. The net-enclosed arena keeps up to 200 pounds of kids from flying out when they do point-saving dives or mini-monster slam dunks. Includes the air blower and stakes to secure it to the ground. $599 only from Hammacher.
