For those of you who don't know NJ, Jackson is home to Six Flags Great Adventure which also includes Six Flags Animal Safari. Though Six Flags doesn't know if the Baboon is theirs (how can they not have a head count ), I think it is. What Six Flags Safari Animal doesn't dream of one day escaping and making it to the "big league" and reside at Animal Kingdom.
Sorry I know this is stupid, but it's the first thing I thought when I read it.
Wishin' I was at WDW!
