On March 24, 2008, Arlington County firefighters used a fire extinguisher to freeze a rattlesnake that bit Andrew Bacas, crew coach at Yorktown High School. Bacas, 49, was unpacking his duffel bag after a team trip to South Carolina. A 10-inch-long rattler had stowed away in the bag - and bit his right hand. According to The Washington Post: ``Using a 10-foot pole, rescue workers gingerly unzipped the duffel bag, just enough to slip in the nozzle of a carbon dioxide extinguisher.''
