Rosenberg Residence - "canine restraint structure"

I dropped off this mobile gate yesterday at the Rosenberg residence yesterday. Tracy had asked me last fall to start thinking of a dog gate for the coming spring. The oxidized finish matches the planter I fabricated for them last October. The switch grass negative image plays on actual organic elements placed in the planter box. To keep one's hands from getting rusty when moving, I sought out a couple of smaller tree limb crotches and attached them with some wood lags from behind. 1 1/2" sq. tube, 11 ga. mild steel plate, 3" x 3" x 1/4" angle and 2" swivel casters.
