Driving the Seven Mile Bridge

Recorded in 2012, this video features multiple views of my driving this bridge. I used 3 SD cameras here (one Black & White) and 3 DVD "set top" video recorders to capture the video. The video here features all 3 cameras in 1080P to keep the images from being too small.
