Region is most commonly found as a term used in terrestrial and astrophysics sciences also an area, notably among the different sub-disciplines of geography, studied by regional geographers. Regions consist of subregions that contain clusters of like areas that are distinctive by their uniformity of description based on a range of statistical data, for example demographic, and locales. In astrophysics some regions have science-specific terms such as galactic clusters.

In Geography, regions can be broadly divided by physical characteristics (physical geography), human impact characteristics (human geography), and the interaction of Humanity and the environment (environmental geography). Geographic regions and subregions are mostly described by their imprecisely defined, and sometimes transitory boundaries, except in human geography where jurisdiction areas such as national borders are clearly defined in law.

Apart from the global continental regions, there are also hydrospheric and atmospheric regions that cover the oceans, and discrete climates above the land and water masses of the planet. The land and water global regions are divided into subregions geographically bounded by large geological features that influence large-scale ecologies, such as plains and steppes, forested massifs, deserts, or mountainous regions. Subregions describe the areas within regions that are easily distinguished in both the geological and ecological observable features.

James Edward Olliges Jr. (born April 27, 1978), professionally known as Jim James or Yim Yames, is the lead vocalist, guitarist, and primary songwriter of Louisville, Kentucky-based rock band My Morning Jacket.

James grew up in the Highlands Douglass neighborhood of Louisville, attended St. Martha grade school and graduated from St. Xavier High School in 1996. James briefly attended the University of Kentucky, studying art. Prior to forming My Morning Jacket, James was the vocalist and guitarist of Month of Sundays, currently known as Mont de Sundua. As the vocalist, frontman, producer and lead songwriter for My Morning Jacket, James has been instrumental in defining the sound of the band, in particular on their critically acclaimed Z, which he co-produced with John Leckie. He was given an "Esky" for best songwriter in Esquire's 2006 Esky Music Awards in the April issue. James typically plays rhythm guitar, acoustic guitar, and occasional lead guitar on My Morning Jacket songs. He recently played the role of the band leader in the Bob Dylan biopic I'm Not There, singing the song "Going to Acapulco", with Calexico as his backing band, which was featured on the soundtrack of the film. Rolling Stone listed James among their "20 New Guitar Gods" along with fellow My Morning Jacket guitarist Carl Broemel. In 2008, James, along with former My Morning Jacket guitarist and cousin Johnny Quaid, formed Removador Recordings and Solutions record label. The label, as described on its website, functions "on the simple principal of yielding the highest annual percentage of aural joy back into the hearts and minds of investors and shareholders with ease and convenience". He contributed vocals on The Decemberists' 2009 album The Hazards of Love.

Dan Bailey (March 22, 1904 – 1982) was a fly-shop owner, innovative fly developer and staunch Western conservationist. Born on a farm near Russellville, Kentucky, Bailey is best known for the fly shop he established in Livingston, Montana in 1938. Dan Bailey's Fly Shop is still in business today, operated by his son John at 209 West Park Street.

Dan Bailey graduated from the Citadel in 1926 and earned a masters degree in physics from the University of Kentucky. He was a teacher in Missouri when he became interested in fly fishing. His next job brought him to Lehigh University where he was able to pursue trout fishing in the central Pennsylvania chalkstreams. In 1929 while teaching at the Brooklyn Polytechnic Institute he pursued a Ph.D. in Physics from New York University.

While Bailey was in New York, he met and befriended Lee Wulff, another notable fly fisherman. They fished the waters of the Catskills and Adirondacks together and Bailey eventually named a popular series of flies designed by Lee Wulff after him. Bailey learned fly tying while in New York and started teaching classes and selling flies to supplement his income. John McDonald, a noted fly fishing scholar was an early student of Bailey's and became a lifetime friend.
