It is a very small house that I would call a Shack, it looks like someone previously lived in it (a long, long time ago) and there are remains of a bed withe springs coming out of it, a couch that's ripped up, and a chair that is also ripped up.
WARNING**** there may be raccoons inside which won't bother you much but watch out for wild animals, and there is also a lot of SPIDERS! Im not talking about the small ones, we did not go inside for that reason, but there is a window you can peek through if you don't mess with bugs even though there are lots of small spiders on the way in.
I've heard there used to be an airport by the shack, but it is completely gone, but just if you want to visit it, it is through the trees, you will have to walk in the place where there is a gate or a giant log and then around the trees and to your right and it won't be too far until you see it so just keep looking to your right.
The reason the pictures are so blurry (if I can upload them) is because I took a video but I forgot to take any pictures, so they are screenshots from the video that I took! Since I didnt get good pictures, im gonna go back another day and hopefully I can get better pictures.
