My guess is that when this family’s kids were young and lived at home that that pool got a lot of use. But,  like most items that families invest in, pools, above ground trampoline’s, etc… they were popular at first and eventually became little to non used, large obstructions, just sitting on their yards. Because of the pool there’s a tall, wooden fence around their backyard that butts up against my yard. As a next door neighbor I’m very glad they tore it down today. Yes, it wasn’t a visual blight, but boy, did it attract pests!
