Natural High

Natural High was a Chevrolet SSR monster truck owned by Kelvin Ramer out of Salinas, California. The truck debuted in 2005 as Kelvin's first monster truck and Kelvin ran the truck until Time Flys debut in 2009.

Tacoma Incident
In 2009 a piece of the driveshaft of Natural High accidentally broke off and flew into the stands, striking and killing a 6 year old boy at the Tacoma Dome. The fallout of this event led to colored driveshafts being mandatory, Natural High being retired, and even to a good extent the censoring of the Captain's Curse crash in Vegas later that year.
