Ben, that's a photo of GASM, but the Green Lantern extends well out into the parking lot on the right due to it's much larger footprint. And I'm not trying to make Snoo look wrong, but rather stating my case that if a coaster is built out onto a parking lot it is therefore a parking lot coaster.
Where is it written that the entire coaster has to be built on a parking lot to be considered a parking lot coaster? Besides everyone calls the coaster right beside this one, Superman: Ultimate Flight, a parking lot coaster even though only a portion of it was built on the parking lot (although it was a large portion).
