If you have an outdoor swimming pool, you are responsible for the transfer of minors injured or drown?

I could not enter a house with a pool in Arizona. It looks like the pools in the neighboring houses are left open. At least, Google Earth caught opening. I know people cover pools in the north during the winter months for safety and maintenance. Use a pool deck drive relatively expensive (supplies, electricity), if the cover of every day when you left?

Perhaps, if nothing is done to keep the installation as a fence with a locked door.

Safety alert: national recall on certain pool drain covers
