 Probably the swimming pool uses salt for conditioning.
I just returned from The Villages visiting family, and their pool uses salt 
instead of chlorine. They have a bird cage as per regulations.
I also was informed that a lot of houses have extensive lightning rods 
protection on the roofs...I could see the little spikes and grounding system 
on the rooftops
