To Water or Not to Water, that is the Question?

Do you pay for water, some people are fortunate enough to have a well or live someplace where you don't have to pay for water. We have to pay for our water and we have 2 water meters, one for inside water and one for outside water and of course they charge more for outside water, so every summer I'm always in a dilemma, do I want to pay a fortune and keep my lawn green or just save the money and let it go dormant, seriously people IT'S WATER, I'M PAYING A FORTUNE FOR WATER......... The backyard stays pretty green without a lot of water because it gets shade but the front gets full sun and starts to look bad after a few days of hot temps, I'm sure our neighbors just love us!
 Is it worth it to you to pay high water bills to keep your lawn green all summer?
