Blockader crowd control barricades, located outside the entrance of the Georgia Dome. One is outfitted with a barrier jacket providing directional guidance to patrons.  Interlocking steel barriers are ubiquitous at stadiums and arenas, inside and out.  Here, they provide blockage and direction at the stadium entrance.  Outside, they are also used at ticket lines and parking lots. Inside, they are used at food and souvenir stands.  Many sports venues also outfit their barriers with jackets featuring the name of the stadium.  Barrier jackets are also used to convey information about stadium policies, or provide fans with directions from one part of the stadium to another.Dsc01630 1
