Join Pima County firefighters as they battle it out to see who will get the bragging rights of best chili in Tucson for the Tucson Firefighter's 20th Annual Chili Cook-Off this Saturday, Oct. 17 at Reid Park (900 S. Randolph Way). They serve more than 750 gallons of chili at the event which attracts nearly 10,000 people to enjoy the food and music. Thirty different booths will be open to test the various personal flairs each firefighter puts on their chili. All proceeds go to benefit Tucson Firefighter's Adopt-a-Family program which assists needy families struggling through the holiday season. For more info, visit the Facebook event page.
