One 11-man team has possession of the football. It is called the offense and it tries to advance the ball down the field-by running with the ball or throwing it - and score points by crossing the goal line and getting into an area called the end zone. The other team (also with 11 players) is called the defense.
Is it one public county pool to 142,000 residents, or one pool for every 35 people here at any point in time. The economic downturn hit Las Vegas hard after a rapid rise for years and is now on a slow recovery. I would not think there are a lot of new pools being built, especially with a water shortage again.
At the San Alfonso del Mar resort in Chile, a quick dip could well turn into a marathon. Swimming a length in this, the world's largest outdoor pool, would mean stroke after stroke for more than three fifths of a mile - that's 20 Olympic-size swimming pools.
