Welke Airport (FAA LID: 6Y8) is a privately owned public use airport located on Beaver Island in Charlevoix County, Michigan, United States.
 Scheduled passenger service to Charlevoix Municipal Airport in Charlevoix, Michigan is provided by Island Airways.
The United States Federal Aviation Administration (FAA) has a system for categorizing public-use airports (along with heliports and other aviation bases) that is primarily based on the level of commercial passenger traffic through each facility.
 It is used to determine if an airport is eligible for funding through the federal government's Airport Improvement Program (AIP).
 Fewer than 20% of airports in the U.S. qualify for the program, though most that don't qualify are private-use-only airports.

The Champaign-Urbana Mass Transit District is a mass transit system that is part of the Champaign-Urbana Metropolitan Area in which property taxes are levied to support a local transit system operating buses and the Illinois Terminal intermodal facility in downtown Champaign.
 Known locally as "MTD," the term also applies to the Board of Trustees or to the administration and operations supported both by these taxes as well as other revenues, such as bus fares.
 At the University of Illinois at Urbana-Champaign, which lies within the District, all 42,883 students pay a $59 transportation fee every semester in 2014-2015 in exchange for unlimited use of the bus services.
 The District currently levies about 28 cents of property taxes per $100 of assessed valuation.
 The seven members of the Board of Trustees are appointed by the Champaign County Board.
 Although Willard Airport lies outside the boundaries of the district, MTD offers District residents bus service to and from the airport on routes funded by the University.
 Buses are produced by the Canadian company New Flyer, Eldorado, and Gillig.
 MTD introduced hybrid buses to its fleet in Fall 2009, while sprinter vans are produced by Mercedes-Benz.
