The relentless guitar is nearly deafening. Chug chug CHUG. Chug chug CHUG. Ch-ch-ch-ch-ch-ch-chug CHUG CHUG. But for an unexpected moment its barking lets up. My truck just jettisoned off a ramp and is now soaring high above the track. The perpetual guitar riffing fades away and the sound of the wind can be heard. Everything is peaceful up here. Before long, however, the ground gets closer until soon enough my truck’s wheels hit the dirt and I continue to barrel forward. Chug chug CHUG. Chug chug CHUG. Ch-ch-ch-ch-ch-ch-chug CHUG CHUG. It’s full speed ahead for both the truck and the guitar.
