The city may be divided on where the first coffee of the day comes from: Starbucks? Dunkin' Donuts? Local caffeine purveyor? Everyone can agree that a free coffee is welcome, though -- especially with prices per cup running about the same as per gallon gas.

0805freecoffee.jpgTomorrow Dunkin' Donuts is offering free 16-ounce iced coffees from 10:00 a.m. to 10:00 p.m. at participating locations for their second annual Free Iced Coffee Day. They're also using the day to announce their partnership with the National Police Athletic League by making an $80,000 donation to support the nonprofit's Youth Leadership Program, which provides grassroots community service and peer-to-peer education to disadvantaged youth. The New York City chapter is one of sixteen receiving $5,000 grants. Visit their website to find your nearest location to score a free iced coffee.

The company tells us that if you lined up each cup of iced coffee served on Free Iced Coffee Day lid-to-lid, the line would stretch for more than 236 miles; or if you'd rather, stacking the cups on top of one another they would reach nearly 300 miles into the sky, the vantage point of a typical space shuttle orbit. So, um, try to bring your own mug to cut down on waste...
