Jeff Gallagher of Integrated Fabric Structures moves a light fixture out of the way as he lowers a lift from the ceiling of the Tennis Dome in Red Deer on Thursday. Gallagher and coworker Gerald Trackl of Edmonton were installing insulation in the walls of the structure which covers four courts at the Red Deer Tennis Club. The $600,000 building will allow tennis players in the city to enjoy their sport year round. The facility should be ready for its first users by next week.
