I must find a way to get to Chicago this November; the Festival of Maps sounds huge:

Opening November 2, 2007 and continuing into 2008, the Festival of Maps Chicago is a citywide celebration of humanity’s greatest discoveries and the maps that record our boldest explorations.

More than 25 cultural and scientific institutions join a unique collaboration that will feature maps, globes, artifacts and artworks and track the evolving technology of wayfinding from ancient to modern times.
