Custom Coasters, Inc. (CCI) went bankrupt while building the New Mexican Rattler. This left the roller coaster less than half complete. Cliff's Amusement Park then finished the construction on their own and the New Mexican Rattler opened late in the 2002 season. An interesting historical significance of this event is that if Cliff's did not get the roller coaster completed by the end of the 2002 season this would be the first time since at least 1985 that a new wooden roller coaster would not have been built in the United States. "At least" is mentioned because at the time of this writing no new wooden roller coasters were known to have been built in North America in 1985 or 1984. The next jump goes back to 1977.
