Cycling is popular in Tucson due to its flat terrain and dry climate. Tucson and Pima County maintain an extensive network of marked bike routes, signal crossings, on-street bike lanes, mountain-biking trails, and dedicated shared-use paths. The Loop is a network of seven linear parks comprising over 100 mi (160 km) of paved, vehicle-free trails that encircles the majority of the city with links to Marana and Oro Valley. The Tucson-Pima County Bicycle Advisory Committee (TPCBAC) serves in an advisory capacity to local governments on issues relating to bicycle recreation, transportation, and safety. Tucson was awarded a gold rating for bicycle-friendliness by the League of American Bicyclists in 2006.
How many miles of trails are in The Loop?
over 100

In 1950, Hayek left the London School of Economics for the University of Chicago, where he became a professor in the Committee on Social Thought. Hayek's salary was funded not by the university, but by an outside foundation. University of Chicago President Robert Hutchins was in the midst of a war with the U. of Chicago faculty over departmental autonomy and control, and Hayek got caught in the middle of that battle. Hutchins had been attempting to force all departments to adopt the neo-Thomist Great Books program of Mortimer Adler, and the U. of Chicago economists were sick of Hutchins' meddling. As the result the Economics department rejected Hutchins' pressure to hire Hayek, and Hayek became a part of the new Committee on Social Thought.
Upon leaving London, for what college did he choose to work?
University of Chicago

A reconciliation of these views is suggested by William Atwood: "Undoubtedly [Chopin's] use of traditional musical forms like the polonaise and mazurka roused nationalistic sentiments and a sense of cohesiveness amongst those Poles scattered across Europe and the New World ... While some sought solace in [them], others found them a source of strength in their continuing struggle for freedom. Although Chopin's music undoubtedly came to him intuitively rather than through any conscious patriotic design, it served all the same to symbolize the will of the Polish people ..."
