Niagara Falls (Cayuga: Gahnawehtaˀ or Tgahnawęhtaˀ ) is the collective name for the Horseshoe Falls and the adjacent American Falls along with the comparatively small Bridal Veil Falls. Located on the Niagara River which drains Lake Erie into Lake Ontario, the combined falls form the highest flow rate of any waterfall in the world, with a vertical drop of more than 165 feet (50 m). Horseshoe Falls is the most powerful waterfall (vertical height along with flow rate) in North America. Niagara Falls forms the international border between the Canadian province of Ontario and the U.S. state of New York, also forming the southern end of the Niagara Gorge. The falls are located 17 miles (27 km) north-northwest of Buffalo, New York and 75 miles (121 km) south-southeast of Toronto, between the twin cities of Niagara Falls, Ontario, and Niagara Falls, New York.

Niagara Falls are composed of two major sections, separated by Goat Island: the Horseshoe Falls on the Canadian side and the American Falls on the American side. The smaller Bridal Veil Falls are also located on the American side, separated from the main falls by Luna Island. The international boundary line was originally drawn through Horseshoe Falls in 1819, but the boundary has long been in dispute due to natural erosion and construction.

David Howell Evans (born 8 August 1961), more widely known by his stage name The Edge (or just Edge), is a musician best known as the guitarist, backing vocalist, and keyboardist of the Irish rock band U2. A member of the group since its inception, he has recorded 12 studio albums with the band and has released one solo record. As a guitarist, The Edge has crafted a minimalistic and textural style of playing. His use of a rhythmic delay effect yields a distinctive ambient, chiming sound that has become a signature of U2's music.

The Edge was born in England to a Welsh family, but was raised in Ireland after moving there as an infant. In 1976, at Mount Temple Comprehensive School, he formed U2 with his fellow students and his older brother Dik. Inspired by the ethos of punk rock and its basic arrangements, the group began to write its own material. They eventually became one of the most popular acts in popular music, with successful albums such as 1987's The Joshua Tree and 1991's Achtung Baby. Over the years, The Edge has experimented with various guitar effects and introduced influences from several genres of music into his own style, including American roots music, industrial music, and alternative rock. With U2, The Edge has also played keyboards, co-produced their 1993 record Zooropa, and occasionally contributed lyrics. The Edge met his second and current wife, Morleigh Steinberg, through her collaborations with the band.

Nikolas Wallenda, known as Nik Wallenda born January 24, 1979 is an American high wire artist, acrobat, daredevil and Guinness Book of Records world record-holder. A direct descendant of Karl Wallenda (founder of the The Flying Wallendas), Nik is known for performing death-defying stunts on highwire without a safety net. On October 15, 2008, during a live broadcast of Today, Wallenda walked and then bicycled across a suspended highwire 13 and 1/2 stories above the ground off the roof of the Prudential Center in Downtown Newark, New Jersey for a Guinness Book of Records world record for longest and highest bicycle on a highwire.

Wallenda, born in Sarasota, Florida, began performing with his family at an early age. As the seventh generation of the Wallenda Family, he first performed at the age of two (dressed as a clown), began walking the wire at age 4 and had his first professional wire performance at 13. In 1998, while 19 years old, he participated in the re-creation of Karl Wallenda's seven-person pyramid on the highwire in Detroit, Michigan by his father Terry and mother Delilah and decided to make a career of it.
