We're in Florida right now, so I mailed our ballots back to the Registrar's physical office - not to the PO Box on the ballot envelope - in a Priority Envelope with signature required. I figured that would frustrate any curious postal workers. It was worth the $5+. Our daughter, who normally votes by mail within Calif, decided to take hers to the poll tomorrow, instead of "trusting" the postal service.
What a sad time.
