Input: Question: How far is it from the beginning of the glen to it's end? Passage 1:LeRae debuted in Pro Wrestling Guerrilla (PWG) in 2006, when she put together a team to face a team managed by Jade Chung in an eight-man tag team match, where her team was victorious. In April 2007, she returned as the valet of Human Tornado. Her first main storyline in the company began later that year in September; Tornado had been abusing LeRae, who stood up for herself and cost Tornado a match at the 2007 Battle of Los Angeles. After the match, Tornado began to attack LeRae, who was saved by Chris Hero. As a result, Hero and LeRae united to take on Tornado. In January 2008, Tornado, Claudio Castagnoli, and Eddie Kingston defeated LeRae, Hero, and Necro Butcher in a six-person match, which meant that LeRae was forced to face Tornado in a singles match the following night. LeRae lost the match by disqualification when Hero, who was banned from ringside, came to the ring to aid her. LuFisto entered the feud in March when she teamed with Tornado in a loss to LeRae and Hero. The following night, LeRae defeated LuFisto in a singles match. LeRae continued to be involved in the storyline between Hero and Tornado over the next few months.
Passage 2:Glen Tilt (Scottish Gaelic: Gleann Teilt) is a glen in the extreme north of Perthshire, Scotland. Beginning at the confines of Aberdeenshire, it follows a South-westerly direction excepting for the last 4 miles, when it runs due south to Blair Atholl. It is watered throughout by the Tilt, which enters the Garry after a course of 14 miles, and receives on its right the Tarf, which forms some beautiful falls just above the confluence, and on the left the Fender, which has some fine falls also. The attempt of George Murray, 6th Duke of Atholl to close the glen to the public was successfully contested by the Scottish Rights of Way Society in 1847. The massive mountain of Beinn a' Ghlo and its three Munros Carn nan Gabhar (1129 m), Braigh Coire Chruinn-bhalgain (1070 m) and Carn Liath (975) dominate the glen's eastern lower half.
Passage 3:Linley launched him on his public career in spring 1784, at first in the Handel memorial concerts at Westminster Abbey and the Pantheon, and then at Theatre Royal, Drury Lane, where he first appeared as Young Meadows in Love in a Village: 'His figure was rather unfavourable for the part, but his voice was so clear and full-toned, and his manner of singing so judicious, that he was received with great applause.' His next role was Cymon in Michael Arne's opera. In a busy first year he was well-received, appearing in various roles, and made his place alongside many well-established performers. 'On the removal of the elder Bannister to the Royalty Theatre, Dignum succeeded to a caste of parts more suited to his person and his voice, which was a fine tenor. Amongst other characters those of Hawthorn' (Love in a Village) 'and Giles' (The Maid of the Mill) (libretti by Isaac Bickerstaffe, 1762 and 1765 respectively) 'particularly suited him: indeed he was thought superior in them to any actor that had appeared since the days of John Beard, their original representative.' Dignum was the original performer of Crop the miller, in Stephen Storace's No song, no supper, and of Abdalla in Storace's Dido, Queen of Carthage. He was also well known as Tom Tug in Dibdin's The Waterman, in which role there is an illustration of him in the Garrick Club.
