A friend was telling me that some people in Las Vegas have created lakes for small communities and mansions. What a total waste of water. Its so wrong to waste water like that when we have to conserve water. You know they've taken water from Utah and California in order to make these lakes! Vegas is in the middle of a desert for h*ll sakes - if they don't want to live in a desert, then they should MOVE! One of the effects that these lakes have on the weather, is making it humid. Where it was very dry heat before, now its sticky hot. Don't mess with Mother Nature - she'll bite you in the a**!
