My husband is starting to make plans to build our Ladies a new run this summer. He was looking at using treated lumber, but I don't know if that is safe to have around the Ladies or not. There are big notices saying that it has arsenic used in treating it, and that you need to use safety precautions while cutting it etc. I really have my worries about using that type of wood . Should he continue to look at it and price it out? Or should he look at a different type of lumber all together....
