dark days

“dark days” means those days when racing of the same type does not occur in an off-track State within 60 miles of an off-track betting office during a race meeting, including, but not limited to, a dark weekday when such racing association or associations run on Sunday, and days when a racing program is scheduled but does not take place, or cannot be completed due to weather, strikes and other factors not within the control of the off-track betting system;
