Question: Was Viborg Ff still operational when Burns earned a place in his first All-Star game? Passage:In 1995, the MLS began an expansion plan to add new teams to the league. In the 1996 MLS Inaugural Allocations, the MLS assigned Burns to the New England Revolution. In August 1995, the MLS loaned out Burns to Danish club Viborg FF. The Revolution retained his rights and Burns returned to play for the Revolution in 1996. In 1998, Burns earned a place in the MLS All-Star game. In the 1999 off-season, he made several attempts to move back to a European club, trying out with clubs such as Utrecht, Bolton and Hearts. None of the clubs expressed interest in him and Burns returned to the Revolution. In June 2000, the Revolution traded Burns, Dan Calichman and a first round draft pick to the San Jose Earthquakes in exchange for Mauricio Wright. Burns finished the 2000 season with the Earthquakes. However, he did not remain with the team and he was traded in March 2001 to the Kansas City Wizards in return for conditional picks in the 2002 MLS SuperDraft. Burns played two seasons with the Wizards, 2001 and 2002. In 2002, he was chosen to play in the 2002 MLS All-Star Game. At the end of the 2002 season, Burns announced his retirement from professional football.

Question: Has the maple leaf been used on any other coat of arms or country flags besides in Canada? Passage:The maple leaf has been used as a Canadian emblem since the 18th century. It was first used as a national symbol in 1868 when it appeared on the coat of arms of both Ontario and Quebec. In 1867, Alexander Muir composed the patriotic song "The Maple Leaf Forever", which became an unofficial anthem in English-speaking Canada. The maple leaf was later added to the Canadian coat of arms in 1921. From 1876 until 1901, the leaf appeared on all Canadian coins and remained on the penny after 1901. The use of the maple leaf by the Royal Canadian Regiment as a regimental symbol extended back to 1860. During the First World War and Second World War, badges of the Canadian Forces were often based on a maple leaf design. The maple leaf would eventually adorn the tombstones of Canadian military graves.

Thomas was born in Stockport, England but was raised in Markham, Ontario, Canada where he attended Markham District High School.

He played junior hockey for the Toronto Marlboros of the OHL (he was the last original Toronto Marlboro to make it to the Maple Leafs of the NHL). Prior to playing in the NHL, Thomas won the Dudley "Red" Garrett Memorial Award in 1985 as the top rookie in the American Hockey League, while playing for the St. Catharines Saints.
