Day 3 of the sixth annual Pitchfork Music Festival, which began in 2005 as Intonation, is under way in the sultry summer heat. A noontime thunder shower moved through quickly, cooling things off for a matter of moments before the sun returned and added the evaporated rain to the day's humidity totals.

Water remains at half price, a dollar a bottle. Still, the line for the free water is longer than that for the bottled variety. Pitchfork staffer (and occasional Sun-Times contributor) Anders Smith Lindall says festival workers are handing out water bottles to distressed concertgoers when the line gets excruciatingly long.

Those who don't mind earning their reward -- and helping to keep the park clear of debris -- can earn one beverage ticket (worth a buck, for one bottle of water) for every 10 discarded plastic cups collected and returned to the recycling booth.
