ICF canoe marathon is an International Canoe Federation governed sport in which athletes compete over long distances.
 The race usually starts and ends at the same place, and includes portages. Race categories vary by the number of athletes in the boat, the length of the course, and whether the boat is a canoe or Kayak.
 In a kayak, the paddler is seated in the direction of travel, and uses a double-bladed paddle.
 In a canoe the paddler kneels on one knee with the other leg forward and foot flat on the floor inside the boat, and paddles a single-bladed paddle on one side only.
 The World Championships were held every two years from 1988, becoming annual in 1998.

 It is the physically largest neighborhood in Buffalo.
 It is characterized by many large, ornate 19th-century churches, most of them Roman Catholic; and modest 1 ⁄ -story wood-frame cottages, many with progressively smaller rear additions that give the houses a telescoping effect.

Butler Place Historic District is located east of the central business district in Fort Worth, Texas.
 Before the housing community was built, the area was known as Chambers Hill.
 In the 1930s, Chambers Hill was notorious for squalid housing and prostitution.
 In 1938, as a result of the dire circumstances in the area, the Fort Worth Chamber of Commerce lobbied the Public Works Administration to help clear the dilapidated housing in Chambers Hill and replace it with low-rent housing.
 Financed by local and federal money, Butler Place opened in 1941.
 When it opened, rents ranged from $15.50 to $16.75 per month.
 The housing project was named after Henry H. Butler, an educator and Civil War veteran, who settled in Fort Worth after the war.
 It was added to the National Register of Historic Places on August 4, 2011.
