The Denver, South Park, and Pacific Railroad (later called the Denver, Leadville and Gunnison Railway) was a historic narrow gauge railroad that operated in Colorado in the western United States in the late 19th century.
 The railroad opened up the first rail routes to a large section of the central Colorado mining district in the decades of the mineral boom.
 The railroad took its name from the fact that its main line from Denver ascended the Platte Canyon and traversed South Park.
 Founded in 1872 by Colorado Governor John Evans, the company was purchased by the Union Pacific Railway in 1880, though it continued to be operated independently.
 The line went bankrupt in 1889 and was reorganized under the new moniker the Denver, Leadville and Gunnison Railway.
 When the Union Pacific went bankrupt in 1893, the DL&G lines went into receivership and were eventually sold to the Colorado and Southern Railway.
 In the first half of the 20th century, nearly all the company's original lines were dismantled or converted into .
 The last train to run the old DSP&P tracks was from Como, Colorado on April 11, 1937.
 A section of the standard gauge line between Leadville and Climax is still operated as a passenger excursion railroad called the Leadville, Colorado and Southern Railroad.
 At its peak the Denver, South Park and Pacific Railroad had 335 mi of narrow gauge line, making it the largest narrow gauge railroad in the state of Colorado.

The Denver Dry Goods Company, also known as "The Denver", was established in Denver, Colorado in 1879 by Michael.
 J. McNamara and L.H. Flanders as M.J. McNamara & Company and later The McNamara Dry Goods Company.
 The beginnings of the company can be traced back to 1876 when they had both worked as clerks at another dry goods store in Denver.
 In 1877, McNamara left that store and formed a partnership with Edgar H. Drew.
 After two years, Drew left and L. H. Flanders came on as co-owner.
 In 1893, McNamara turned the store's ownership over to Dennis Sheedy and Charles Kountz and in 1894, the company was reorganized under the name, "Denver Dry Goods Company".
 For a while it was claimed to be the largest department store west of Chicago.
 A description on one postcard from 1916 read: "The Largest Store in the Central West, 400 Feet long-Seven Acres Floor Area, 1,200 Employees, A $1,500,000 Stock, 15th to 16th on California Street Denver Colorado".

 She succeeded her father, Frederick Gilmer Bonfils, as manager of "The Denver Post" in 1933, and eventually became president of the company.
 Lacking heirs, she invested her fortune into providing for the city of Denver and the state of Colorado, supporting the Belle Bonfils Blood Bank, the Bonfils Memorial Theatre, the University of Denver, the Denver Zoo, the Dumb Friends League, churches, and synagogues.
 Her estate endowed the Denver Center for the Performing Arts.
 She was posthumously inducted into the Colorado Women's Hall of Fame in 1985 and the Colorado Performing Arts Hall of Fame in 1999.
This is a list of notable employee-owned companies by country.
 These are companies in which employees have an ownership stake.
 For example, an employee stock ownership plan (ESOP) is an employee-owner method that provides a company's workforce with an ownership interest in the company.
 In an ESOP, companies provide their employees with stock ownership, often at no up-front cost to the employees.
 ESOP shares, however, are part of employees' remuneration for work performed.
 Shares are allocated to employees and may be held in an ESOP trust until the employee retires or leaves the company.
 The shares are then sold.

The Chicago and North Western Transportation Company (reporting mark CNW) was a Class I railroad in the Midwestern United States.
 It was also known as the North Western.
 The railroad operated more than 5,000 miles (8,000 km) of track as of the turn of the 20th century, and over 12,000 miles (19,000 km) of track in seven states before retrenchment in the late 1970s.
 Until 1972, when the company was sold to its employees, it was named the Chicago and North Western Railway (or Chicago and North Western Railway Company).
Employees typically must relinquish some of their privacy while at the workplace, but how much they must do so can be a contentious issue.
 The debate rages on as to whether it is moral, ethical and legal for employers to monitor the actions of their employees.
 Employers believe that monitoring is necessary both to discourage illicit activity and to limit liability.
 Although, with this problem of monitoring of employees, many are experiencing a negative effect on emotional and physical stress including fatigue, lowered employee morale and lack of motivation within the workplace.
 Employers might choose to monitor employees activities using surveillance cameras, or may wish to record employees activities while using company owned computers or telephones.
 Courts are finding that disputes between workplace privacy and freedom are being complicated with the advancement of technology as traditional rules that govern areas of privacy law are debatable and becoming less important.
The City of Denver was a streamlined passenger train operated by the Union Pacific Railroad between Chicago, Illinois and Denver, Colorado.
 It operated between 1936 and 1971.
 From 1936–1955 the Chicago and North Western Railway handled the train east of Omaha, Nebraska; the Chicago, Milwaukee, St. Paul and Pacific Railroad (the "Milwaukee Road") handled it thereafter.
 The train was the fastest long-distance train in the United States when it debuted in 1936, covering 1048 mi in 16 hours.
 For almost its entire career its principal competitor was the Chicago, Burlington and Quincy Railroad's "Denver Zephyr".
 When Amtrak assumed operation of most intercity trains in the United States in 1971 it discontinued the "City of Denver", preferring to use the Burlington's route between Chicago and Denver.
