What is it with people who put pools up and hardly use them?

Cape May County - What is it with people who put pools up and hardly use them? I mean what's the sense when the maintenance and pool supplies, not to mention the electric it costs to run the pumps and such all adds up to being more than the time you spend in it. I mean you don't even swim. It just sits there cording away, wasting away.... ya'll can keep that headache.
