It's the same type of pool that ranch and farm kids have played in for years. My mother, a rancher's daughter, had one growing up.
Oh, you expected a real pool? Ha. Not happening for years...unless we win the lottery. It's a galvanized feed stock tank and I have to say, it works really well. It fits the four of us with enough room for a rowdy game of "Marco Polo." Plus, it adds character to our little piece of property. Why buy an inflatable pool from a store when you can get a galvanized feed tank from the farm supply store?
