This photo provided by Ryan Reede shows smoke from a fast-moving brush fire that Reede took as he was riding on a roller coaster at Six Flags in Valencia, north of Los Angeles. The brush fire erupted near the huge amusement and water park in Southern California on Sunday, sending hundreds of visitors to the exit to escape clouds of smoke and ash before fire officials asked them to stay put while they worked to contain the blaze.
