What's That Infrastructure?

Ever see some piece of infrastructure and wonder "What is that?" There's a whole world of man-made facilities, structures, and utilities that exists right under our noses. "What's That Infrastructure" is a new video series where I take photos of infrastructure from viewers and try to explain what it is, how it works, and why we need it in our lives. If you have a picture of something interesting, use the email below to send it in! Maybe you can stump me...
