Portland

Portland, Oregon’s largest city, sits on the Columbia and Willamette rivers, in the shadow of snow-capped Mount Hood. It’s known for its parks, bridges and bicycle paths, as well as for its eco-friendliness and its microbreweries and coffeehouses. Iconic Washington Park encompasses sites from the formal Japanese Garden to Oregon Zoo and its railway. The city hosts thriving art, theater and music scenes.
The city covers 145 square miles (380 square kilometers) and had an estimated population of 639,863 in 2016, making it the 26th most populous city in the United States. Approximately 2,424,955 people live in the Portland metropolitan statistical area.

Roughly 60% of Oregon's population resides within the Portland metropolitan area.

The city operates with a commission-based government guided by a mayor and four commissioners as well as Metro, the only directly elected metropolitan planning organization in the United States. The city government is notable for its land-use planning and investment in public transportation. Portland is frequently recognized as one of the world's most environmentally conscious cities because of its high walkability, large community of bicyclists, farm-to-table dining, expansive network of public transportation options, and over 10,000 acres (4,000 hectares) of public parks. Its climate is marked by warm, dry summers and cool, rainy winters.

1845 Portland got its name in a coin toss.  
Portland was initially referred to as "Stumptown" because of the many trees cut down to allow for its growth.  Francis W. Pettygrove and Asa Lawrence Lovejoy wished to rename Stumptown after their respective hometowns (Lovejoy's being Boston, and Pettygrove's, Portland). This controversy was settled with a coin toss which Pettygrove won in a series of two out of three tosses, thus Portland.
