Photo editor Karen Callaway spent the last four years documenting the eve of the Feast of Our Lady of Guadalupe from groups leaving their parishes and making the pilgrimage to the shrine in Des Plaines and back to their parishes again. This slideshow shows what goes on through the night during a pilgrimage that draws tens of thousands of people each year.
