Nissan '#AltimaWeekendContest' by TBWA\Chiat\Day LA

In 30-second spots, the automaker presents clues to win an epic weekend adventure

Nissan is asking eagle-eyed TV viewers to guess what specific stops a couple made on a road trip in a series of TV spots by TBWA\Chiat\Day LA.

Each ad begins with the couple frantically leaving their Altima sedan — the last moments of a roadtrip that started on Friday at 5pm and ended minutes before they have to return to their office.

A different set of distinct items are in the back seat, challenging clever viewers to trace the couple's journey.

The ads ask online sleuths to guess via Twitter the five stops the couple made, using the hashtag #AltimaWeekendContest. A correct guess could lead to a re-creation of the roadt trip, courtesy of the automaker.
