On Friday, May 29th, drivers in Gumball 3000, an international supercar rally, completed the last leg of their 3,000 mile journey through Death Valley National Park, ending in Las Vegas. Rangers patrolled the Highway 190 corridor in both marked and unmarked vehicles and were assisted by a California Highway Patrol airplane. During the event, rangers issued over a dozen citations for violations such as speed and unsafe operation and observed vehicles traveling as fast as 140 mph.
