They haven't complained... But they wouldn't have a leg to stand on. The one to the west, has a Mexican rodeo stadium, which is active nearly every weekend with 800 or 1000 people, mariachi bands, huge bonfires, and the whole enchilada. The neighbor behind us has a rifle range on his place, and has drunken shooting parties. And let's not forget the Cuban mafia man, who just imported (ILLEGALLY) a few thousand yards of dirt, backfilled a federally-protected waterway, and God knows what else he's up to. So nobody dares complain about my innocent little sirens ;-)
And we're not in a noise-regulated zone. If anyone moves into the area, and thinks about complaining, I'll point out that the name of the road is Wailing Siren Ranch Drive.
