There are a number of projects going in this area right now, but nothing regarding Hank Williams Jr. as far as I could see. HANK could also be cryptic for a specific scene being shot at a location rather than the actual production's name.
An bit of info though, for those who weren't aware, Hank Williams Jr. was actually born in Shreveport while his father, the legendary Hank Williams Sr. performed on the Louisiana Hayride. Hank Jr. spent part of his childhood living in Old Bossier, a now mostly rundown neighborhood located next to the Louisiana Boardwalk shopping area. The Old Bossier neighborhood is part of what was once the original Village of Bossier City, long before Bossier City had 60,000 residents.
