Republican presidential nominee Mitt Romney and running mate Paul Ryan plan to appear Saturday at a rally at the Landing. Doors open at 2:30 p.m. and the event begins at 4:30 p.m. Tickets are free but are required. They are available at jacksonvillevictoryrally.eventbrite.com. The site said attendees will be screened through “airportlike security” and should bring few personal items. Cameras are allowed, but bags, sharp objects, umbrellas, liquids and signs will not be permitted. Romney and Ryan accepted their party nominations this week during the Republican National Convention in Tampa.
