Below are pictures from a day of karting at Thunder Alley. This particular day, the regular crew was joined by professional rally co-driver Therin Pace, who competed in the 2004 World Rally stage in Mexico.

Troy Samuelson and his dad, Todd, line up on the front row for a short sprint race.

Steve Bonano (#11) sticks his nose in too.

The color of the track shows the rubber that gets put down by the tires.
