CHICAGO -- You'll need a ticket if you want to attend Barack Obama's outdoor Election Night event in Chicago.
The campaign sent an e-mail Tuesday inviting only supporters from Obama's home state of Illinois.
To get tickets, people need to sign up at a Web link for a printable ticket that'll be e-mailed before the Nov. 4 event in Grant Park. Only one request per person is allowed.
Gates open at 8:30 p.m. for the event, which will take place in a field at the south end of the lakefront park.
It's unclear how many people are invited, but city officials have said the area can hold between 60,000 and 70,000 people. Prior to the announcement from the Obama campaign, Mayor Richard M. Daley was a little more generous, predicting that more than a million people could descend on the park.
Chicago officials said the event could cost at least $2 million and the Obama campaign has assured them they'll pay for it.
