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.
One that jumped out at me is that on any given year, there is one drowning of a child for every 11,000 residential pools in the United States. What this means is that in a country with 6 million pools, roughly 550 children under the age of ten drown each year. Another more recent study not in the book points out that 10 people a day die from drowning in the United States.
