Naperville, Illinois is one of the best places to live in the United States. This city of 150k sits about 40 miles west of downtown Chicago. It's a yuppie western suburb where a lot of commuters choose to reside. Given that the U.S. is one of the safest and most well-off countries in the world, that's saying a lot. Naperville is one of the best places to live on the planet if you're raising a family. It's a good place to grow up. As far as houses go, 416k is the median price you can expect to pay.
For the same price as 1 above-average home in Naperville, the Rwanda Clean Water project provided clean water to a population equivalent to the whole city of Naperville. This is the good cause that I came across today after surfing over to Fermi Project, whose founder I heard from at a conference today.
