Heifer International is a worldwide organization that has been in existence since, I believe, 1949. They have offices all over the world, so I'd say they're a pretty big organization. Their headquarters will host a wide variety of events; from family reunions, to small seminars, etc. Their facilities are quite nice and set in a beautiful wooded area. The have many different sizes of lodges, from bare minimum facilities to quite complete. They also have a large dining facility, where they serve meals primarily from animals and vegetables raised on site--organically. Their exhibits teach sustainability, inlcluding what to do with waste materials; use them for fertilizer or convert them to gas for cooking. Hugely interesting place! Families that are provided with animals go through a two-year process, from screening for need and ability to care for the animals, to being taught to build housing, to care for the animals, then are required to pass the first-born on to another family. Then then teach that family to care for the animals.
