Dragging them through the water is the easy part... I'm talking about what happens when you get to shore, or the edge of the pool... Taking them out of the water (very much necessary) is a lot harder than pulling them along when they're floating...

Granted, pulling them onto a beach would be much easier than pulling them out of a pool... So that's more likely... But at a pool, even if you try to climb out by the ladder, you've still got to have the strength to basically lift and carry a lifeless body... Not that easy...

Unless you had help (which I'm sure there'd be plenty of people around who'd be willing to lend a hand)...
