As a mom, you may be concerned that Nevada puts little emphasis on education. Nevada consistently rates bottom ten in per-pupil funding, educational achievement and so on. OTOH, Nevada consistently rates top ten in meth use, teenage pregnancy, drop-out rates and so on. Still, wonderful parents raise wonderful children, here. Just know all the facts before making any big decisions.
Then again, you may be a "happy mom" because your children have left the nest.
Living in Boulder City has served me well. It's quiet, peaceful and more stable than the Las Vegas valley.
