He celebrated an early Easter by sending fans on a Twitter scavenger hunt across the country, and he may do it again.  Justin Timberlake tweeted on Friday that he was hiding signed copies of his "The 20/20 Experience" album in various places around the U.S.  Fans sprang into action and found the albums in New York City's Central Park, Los Angeles, San Francisco, Chicago, and near his hometown of Memphis.  None were hidden here in Southern New England, but Justin hints that he may do it again.  So stay tuned.
