A rectangular one-piece garage door has rigid horizontal upper and lower rails and rigid vertical first and second side rails. A small door is mounted in the garage door. A track assembly has horizontal first and second upper tracks. The track assembly has vertical first and second lower tracks. An arcuate first intermediate track couples the first upper track and the first lower track. An arcuate second intermediate track couples the second upper track and the second lower track. First and second upper hinged brackets are secured to the garage door adjacent to the upper rail. First and second lower brackets are secured to the garage door adjacent to the lower rail. Rollers are each coupled to one of the brackets and rotatably received within one of the tracks for guiding the movement of the garage door between a closed lower orientation and an open raised orientation.
