Frogs and crickets/cicadas (at night), lawn mowers, the ping of the metronome for the drumline and marching band, and (most years) the ping of the bat from the high school that basically backs up to our property. I LOVE our location.... Our lot backs up to a very narrow former cow lot that is now being repurposed, but is in the middle of the suburbs, on a street that only gets the traffic of the families who live on it. Close enough to have easy access to multiple major roads, but far enough away to not hear any of it. *sighs contentedly*
