Well, every time anybody comes to our house we have to show them our very own “in-ground swimming pool”. haha. Under our garage there is a cistern. I guess before we had city water, the people would get their water from here. It’s about a 8 ft deep hole under our garage. It’s actually pretty neat….even though we don’t use it or anything. My husband and my sister really want to go scuba diving in it someday but it’s really gross in there. They always joke around about putting in those cute lights on the ceiling and then having our very own pool or hot tub (if we heat it…) haha.
