As noted on the related Facebook group, the application to the PB has been withdrawn.

Not a surprise as they have to start over with a new application to the ZBA and the PB can not accept an application as complete unless and until the ZBA approves a special exception to allow the commercial event facility in the rural zone.
Will they be back?? Does a bear s##t in the woods?
When they do submit to the ZBA, written comments become part of the recorded. Comments should focus on the specific criteria that must be found true to grant a special exception. See page 75 of the zoning regulations.
