Later that evening at a different go-cart place in Pigeon Forge. This time I decided to join them. We're in the first 3 cars and were just about to get the green light to start. This race track was a 4-level parking garage style with a steep, straight drop from the top level down to the lowest level at the end. I went thru the whole thing 5 or 6 times during that one race, while Chris "lapped" me once and almost a second time before it was over. My car experienced gas & brakes; Chris' car experienced ONLY "gas pedal to the floor" the entire time.
