This is my second object mod for GTA IV. There's 162 objects, and it works for GTA IV & both dlc's.

some of the ramps aren't perfectly flush with one another. I re-did
it 3 times, making the loop smooth.. But every time I'd save & load the park
something with the trainer would throw them off..

So I finally said screw it, but you can see in the video it still works great.

Enjoy.
