An annual cross country roadtrip made by hackers on their way to DefCon, a hacker convention in Las Vegas. The original Death Race was only in California, starting with four vehicles in the caravan. Over the next three years, the number of vehicles increased, and though the "official" Death Race is still the one made from California, there are numerous other caravans made from all over North America to the Mecca of hacking conventions in Nevada every summer.
