Was messing around with Bing maps and their bird's eye view. Found a few points of interest far outside King's Island's developed areas. Maybe some of you folks can identify some of this junk?

You can see some trams to the left, as well as the top right. They continue in a line if you pan to the right. If you pan up, there is a nursery, which may or may not be owned by Kings Island. Towards the middle right of the picture you can see a sign in two pieces. I'm not sure what the sign says, but I believe the bottom half has the Nickelodeon logo. Because the different angles were taken at different times, things come and go if you rotate the map. In some of the views, there are some green track pieces which I thought might be from King Cobra.

This is another area of interest. Once again you can see a tram. I take particular notice here of the cars in the top left, which I believe are from king cobra. Rotate the map one time counter clockwise and the area is laden with green track. If I remember correctly, cobras track was eventually scrapped and the cars were sent to another park for spare parts on another togo coaster.

This last one is less discernible. There is a structure with assorted junk to its west. To its southeast there are some pillars. Rotate for better views.
As a local resident, I am tempted to do some exploring. However, there are security vehicles in some of these shots, and I don't think they are there by chance. I have a feeling they patrol these areas a lot.
