I took this shot yesterday near the Galleria area in Houston. I was on the 14th floor of an office when a brief rain shower came through. This rainbow formed right between the building I was in and the one right next to us. Had to grab a couple quick shots. I could look down and see right where the rainbow started at ground lever. Pretty neat.
