This is the note:

> Closed TO NON SKED TRANSIENT GA ACFT EXC PPR 617-561-2500

Which translates to “closed to non-scheduled transient general aviation aircraft, except those with prior permission from calling 617-561-2500”

They just don’t want me flying my Skyhawk in there at 90kts on final, at least without calling them first so they can get some cathartic tongue lashing in before giving me permission.
