Do they matter? I am doing some images based on the Powerage sawmill. There is no topic area for industry and commerce though that has been a topic for art almost as long as art has existed. So a. Why isn't there an area for Industry and b. any suggestions on where I should I put it so I don['t get nasty comments about it not belonging there. (And yes people leave such comments.) It is a big red metal factory complex with ramps pipes multiple stories high. It isn't transportation. It isn't Science and Technology. Suggestions from anyone wiling to be quoted?
