NATO protesters at Chicago's Grant Park douse their caps, fill their water bottles and wait in long lines on a very hot and humid Sunday in Chicago.
As the mercury rose to a sweltering 91 degrees in Chicago, anti-NATO protesters found shelter in the shade of Grant Park.
People were seen waiting in long lines for just four water fountains ahead of the march to McCormick Place led by the Coalition Against NATO/G8 War & Poverty Agenda and Iraq Veterans Against the War.
One woman dipped her hands in a trough to cover herself in water. Others waited in line at an ice cream cart.
Heat remained a big issue as speakers began the groups' protest program at the Petrillo Band Shell. Organizers on stage warned marchers to hydrate as much as possible before starting the walk to McCormick Place.
An evening rain later provided some respite from the heat.
