Back in the 80's a local Woodpecker(who's species uses loudness to definte a good male mate)discovered that the particular transformer used in our town echoed well. Today, pretty much every male uses them during Mating Season(which is NOW). Sadly, they were too successful. Gulf Power is replacing these older transformers as they go with those designed to be less percussive....
