Official Tucson Gem Show Guide funktioniert nicht

With one main event, and more than 40 smaller events throughout Tucson, this app provides visitors with everything they need to know about when and where each event is held, type of event (public, wholesale or both), shuttle and streetcar locations and routes, and dining options.  The gem and mineral show draws international crowds to Tucson, Arizona for two weeks of trading, bargaining and buying—showcasing some of the earth’s most spectacular geologic treasures.  It is the world’s largest, oldest and most esteemed event of its kind.  The interactive map makes navigating and planning a breeze, so guests can get as much out of the gem and mineral show as possible.
