Location(s)

DuPage County Early Voting begins Monday, October 13 and extends through Thursday, October 30.  The location in Naperville Township is the Naperville Municipal Center at 400 S. Eagle. (That's south of the river in downtown Naperville between Eagle Street on the west and Water Street on the east.).  The schedule and list of locations for the whole county is here.  Their page discussing the procedure is here.

If you're going to be out of town or are  otherwise unable to make it to the polling place on Election Day, or even if you just don't feel like facing the crowds that day, Early Voting is your right.  What matters is that you make your voice heard.
