Largest Swimming Pool

The largest swimming pool in the world is located in Algarrobo, Chile. It covers 20 acres!  Just look at it!  No sharks to worry about, no fish nibbling at parts you'd rather they didn't, no jellyfish lurking to sting you.  Looks like you can swim and swim and never run into anyone else!  And is that a sail board?  Couldn't take one of those in the water down at the Y!
