I have quite a few feelings on this, the strongest of which being that THIS IS GOING TO UPSET SO MANY MILITARY LOCALS. Zombie Cannibal Soldiers has so much potential to go wrong I am utterly shocked that the park would consider this. Miner's Revenge, if you don't recall, was a maze last year that upset people hundreds of miles away simply by it's name and blurb on the site. These people never actually saw the maze, but were upset because it was insensitive to their culture. Now, take what happened there, and apply it to the US Military in a town next to one of the largest concentration of bases in the country in addition to the fact that the company that owns the park is already going through a massive PR crisis because they hurt cute animals. I get that the park wants to cater to the local Military population and they have a certain history of supporting the troops, and that's great. This, though, seems like it has a huge potential to insult them.
The best thing really for the park to do is just scrap the whole Military thing. If they were to keep it, there might be a way for the park to do this correctly though, and the park is going to have to put some real effort into this to work. First of all, these soldiers are going to clearly be part of a fictional organization to be non-offensive, something clearly fake like C.B.C.U. (Cryptid Biologic Containment Unit), should be plastered on whatever bases are set up, uniforms, ect. The uniforms should also be completely different from real uniforms. Ideally, all black special ops gear would be the best with no markings to indicate branch or nationality. If you see a picture of them, you should not be able to say, "Well, this is clearly the Navy". The soldiers should also not be out to attack/scare guests, the second word gets out that the park has soldiers terrorizing civilians, it would be very bad. Have whatever scare actors are set up in civilian outfits and have the soldiers trying to protect the guests, kind of like the Constabulary in Ripper Row. I heard mention of security checkpoints, that's good, it makes it seem like the soldiers are there to protect the guests.
As far as the Wendigo idea, I actually really like it. It's original, fits the theme, and even has some roots in local legends (more up north, but still). For those who don't know, the cliffsnotes version of the lore is that a Wendigo is something of a cross between a Werewolf and a Sasquatch. A human is transformed into one if they eat human flesh. It's actually a smart move on the park's part because you can have evil people with minimal makeup and effects. They're going to have to do a bit of work to make it seem like the area is a Military Base, but they kind of pulled it off with Ripper Row last year.
I can not stress just how bad this could potentially be for the park and I urge all the creative heads reading this to consider the potential ramifications of this. If you guys think the Nurse or Blackfish backlash was bad, imagine what would happen if Bill O'Reily or Sean Hannity gets on the air and talks about BGW is mocking the Military.
(Oh hey, no Sasquach DJ jokes)
