Hello Friends, I know the folks in the other parts of the country absolutely need it but do we? It can get pretty stupid hot here too, though we usually don't have the humidity unless we get a storm come up from Mexico (like we just did) I am very seriously considering adding it but I get the feeling it may not be needed MOST of the time. Ive been reading more and more on the Gizmos. Those seem like they work really well. I suppose I can get without for now and add it later if needed...Still like to hear your experiences.
