I just called Parks & Rec. The lady was very nice, and she stated the range is only open on Sat & Sun due to staffing shortages.
So, I pressed her: Are you saying holidays are no longer an exception? In the past, if a holiday fell on a Monday, the range was open, even though Monday is not a regular day to be open.
She said, "I'm not sayin that."
She basically assumed it would be closed, but didn't want to commit to that as the official answer.
She's going to have someone call me back who might know more.
Stay tuned for further developments.
