Happy hunting ground

n. North American Indian heaven, place of peace and utter happiness to which people go after death (belief of some North American Indians); place where much of something desired can be obtained

The happy hunting ground was the name given to the concept of the afterlife by several of the great plains Native American tribes, such as the Iroquois, Cherokee, Algonquian and Sioux. It is an afterlife conceived of as a paradise in which hunting is plentiful and game unlimited.
