Zip lining, zombie paintball just another day on the job for Henderson residents

At the base of Bootleg Canyon, Jeffrey Grasso slings an 18-pound, metal zip line trolley over his back and begins his march to the top of the mountain. A 1,200-foot-long zip line awaits him. He is joined by nine others who are following his lead and listening to his commands. But this isn’t another hike for him — it’s his job.
