"A dream. It's perfect": Helium discovery in northern Minnesota may be biggest ever in North America::For a century, the U.S. Government-owned the largest helium reserve in the country, but the biggest exporters now are in Russia, Qatar and Tanzania. With this new discovery, Minnesota could be joining that list.

Incorrect. It is not found naturally pure, it must be distilled. Balloon helium vs cryogenic helium is like comparing ice distillation vs vapor distillation of liquor. One is cheaper but both are using up a limited resource.
