The kiddie pool — where would our summers be without it? What inflatable object could we blow up into a floppy, neon monstrosity that takes over the whole lawn and looks nothing like the photo on the box? Where would we recline in 3 inches of hose water, and where would we sip our homemade umbrella drinks? Nowhere, that's where. And that's why the plastic paddling pool is king of the summertime lawn.
