It really is a privilege to have a facility like this here in SA!The viewing options you have as a 'general admission' spectator are incredible.The lighting theatrics at night when a record drops are awesome. Even for those that don't follow Drag Racing, you need to experience Top Fuel in person! I can't even begin to imagine what it takes to co-ordinate such an event....Enjoy your Sunday!#sonicinjection #thebend #RBnats2024 ... See MoreSee Less
