I ran across a similar site while investigating old
rollercoasters a while back (that's how I discovered you larky lot).
It's in the USA and was simply closed about 25-30 years ago.
The trees and such grew up around the wooden coaster and a
very rare TumbleBug ride.
I know the trains from the coaster were a seldom seen PTC
(Philadelphia Toboggan Co.) design and were saved by someone.
Not sure about the Tumblebug (turtle version).
Here's the link:

Scroll to the bottom.
Here's a link to the entire site.
There are TONS of photos of overgrown rollercoasters and other rides on this site.
Sit down when you have a couple of HOURS to look this over.
