Chicago [Wikipedia] is the third-largest city in the United States. 2.7 million people live in the city proper, 9.5 million live in the metropolitan area, and the city hosts 45 million visitors in a typical year. The city center is full of sights and activities [Wikitravel] easily reached by walking, thanks to the systematic use of skyscrapers for residences and offices.

Chicago has two major airports: O'Hare (ORD, 10000 Bessie Coleman Drive, 27km from downtown), which handled 66 million passengers in 2012, and Midway (MDW, 5700 S. Cicero, 13km from downtown), which handled 19 million passengers in 2012. O'Hare is one of the best-connected airports in the world, offering flights to more than 60 international destinations and more than 100 domestic destinations. Midway offers flights to more than 60 domestic destinations, notably on Southwest Airlines. Note that Southwest is not visible through most search engines.

Both O'Hare and Midway are conveniently connected to the city center by metro lines operated by the Chicago Transit Authority (CTA). This web page originally continued saying "metro" for general comprehensibility but the reality in Chicago is that nobody says "the metro"; it's the "L" or "El", referring to the fact that many of the tracks run on elevated lines. Taxis are faster but the L is simple and reasonably fast. O'Hare has a Blue Line L connection to the city center and UIC every 10 minutes. Midway has an Orange Line L connection to the city center every 10 minutes. Google Maps has a good understanding of Chicago's public-transportation system, including L and bus schedules. There is also live tracking of L trains and buses.

To find the O'Hare L station from Terminals 1, 2, or 3, look for signs saying Trains to City. The airport train station is underground:

To find the O'Hare L station from Terminal 5 (international arrivals), look for escalators up to the Airport Transit System at the top level. Get off at Terminal 3, and look for signs saying Trains to City.

There is a machine at the O'Hare L station that sells 3-day CTA passes, currently $20, and 7-day CTA passes, currently $28; same for the Midway L station. Sometimes the machine has trouble taking cash but it should still take cards:

These passes provide free travel on the L and on the CTA's bus network. There are also single-ride passes, but the 3-day pass will be the best option for most DIAC 2013 attendees. CTA says that a 3-day pass is valid for 72 hours from first use and does not expire at the third midnight.

All lectures will take place at the University of Illinois at Chicago (UIC), specifically Student Center East (also known as Chicago Circle Center) at 750 S. Halsted Street, Chicago, IL 60607. Student Center East is a 5-minute walk from the UIC L stop on the Blue Line:

Inside Student Center East, go up to the Cardinal Room on the 3rd floor (2 levels above ground):


The next stops from UIC in the O'Hare direction (Clinton, LaSalle, Jackson, Monroe, Washington, Clark/Lake) are next to dozens of comfortable hotels in the city center. Student Center East is also walkable from the city center; for example, it is a 20-minute walk from the Sears Tower. Chicago also has a new bike-sharing system.
