History- Parker can trace its colorful recent history to the establishment of the Pine Grove Post Office by Alfred Butters around 1863. Prior to that time, the area was used for hunting by Indians, including the ancients (prehistoric), the Plains-Woodland Indians, and later (1800's) mostly Arapaho, Cheyenne and Ute.

Although courthouse records bring the dates into question, historical accounts generally agree that George Long traded the 20-Mile House to Nelson Doud in 1870 for a pair of mules. The Doud’s enlarged the place to include ten rooms and a second story ballroom. They sold it in 1874 to James Sample Parker, an ex-bullwacker and station manager who had been living in Kiowa. Under Parker's ownership, the 20-mile House grew and prospered; a blacksmith shop with equipment to shoe oxen and a general mercantile store were added to the facilities. It became the first official post office.

Recreation- Parker is a unique town with a Victorian-Western Mainstreet, perfect for a casual stroll, dining out or shopping. An excellent quality of life with natural open areas, trail systems and recreational activities- and if you are interested in horses—acreage and horse facilities are many.
