Looks like it's abandoned on a logging road
My wife and I do a lot of hiking and invariably see old cars, trucks, strange looking machinery, dumped appliances and so on. Some of the places we've been makes you wonder how that stuff got there, being that these kinds of places are just so far out there. I remember seeing an IBM PS/2 computer just laying in the middle of the woods, at least five miles from any road. Unfortunately it was too far gone but I did take a peek inside and everything was there, including the hard drive. Made me wonder who put in the effort to take it all the way out here and why, as I always wonder when I see random artifacts in the wild.
There's a lot of cool stuff out in the woods. If I see something, I always have to stop and look. Some of the things I've seen are kind of creepy, like elk skulls in this old, rusty Philco fridge I found laying on its side, rickety, eerie shacks or really old cars just daring you to pop the trunk.
If I saw that Kirby, especially it being a 500 series, I'd carry it out of there and all the way back to my rig. I'd love nothing more than to find something like this.
