The nearest major airport is the Will Rogers World Airport.
Taxi, Van and Shuttle service is available from the airport. Check to make sure that they will drive to Norman.
If renting a car, the directions from the airport to Sooner Legends (location of Friday evening's reception and the conference hotel) or from the airport to the parking lot outside of Nielsen Hall (the conference venue) are available.
This naturally depends on where you are going to start. The destination on Friday Night is Sooner Legends Inn & Suites (Google Maps). The conference will be taking place at Nielsen Hall, and parking is available for free in the large lot to the south of Robertson Hall.
A campus map is available in PDF (an interactive version is also available). The primary conference venue is NHN, or Nielsen Hall, which is number 43 on the map. The second conference venue is the Oklahoma Memorial Union (number 20).
There is also a set of directions to campus (specifically, to the OU Visitor Center) and where to park on campus. It also has several different maps of the area.
