I was at Dallas' Galleria Mall on the north side of town when I decided it would be nice to take an image similar to that which I'd take in Grand Rapids.
This was next to I-635 and an exit ramp while I was on the top floor of the parking structure.
Tech Info - I had no tripod but knew I needed long exposures so I found a pipe on the edge of the structure that had no top cap. I rested my camera on the pipe which meant I was sitting on the very edge of the railing.
This was a little nerve racking for someone not very comfortable with heights but I wanted the picture.
