The Wranglers were members of the Central Hockey League for two years, but the years were not back to back. The Wranglers suspended operations after the 1968-69 season. They then returned to the league for the 1970-71 season but again they ceased operations after that season. McGregor and the Penguins tried twice to bring hockey to Amarillo, Texas and each time they have found it costly due to poor attendance.
