I really like this photo, too.
Trained as an engineer, I often find items of an industrial nature attractive, whether trains, planes, automobiles... bridges, highways, even transmission towers. Many articles of infrastructure have been the subject of my camera. Having long been an editorial and commercial photographer, in recent years I've come to do a good bit of work in the field of alternative energy, photographing wind and solar installations.
In fact, when I'm on the road (which, between work assignments and personal travel, I do for most of the year), I'll frequently stop for objects like this that catch my eye. So far, I've been fortunate in that law enforcement has never bothered me. Of course, with my equipment, it's pretty obvious what I am doing, and I'd like to think those who do this sort of thing with evil intent would be a little more clandestine.
