The Red Finger Express, more than twice the size of the previous Sore Thumb Coaster, was built at the Park in Napa (The offices of Full System, Inc.). It took two days to build with five people helping. This coaster was made from parts from seven K'Nex sets: four Roller Coaster sets, two Big Ball Factory sets, and one Trampoline Tower set.

The construction took place over the weekend of April 1, 2001.

To accommodate the height and breadth of the Red Finger Express, the ceiling was opened up to route track up ten feet.

The construction remained up for several weeks creating much comment ensuing a great deal of creative play by employees and clients.
