The Vertigo at Cedar Point collapsed during the offseason a few years back.
The one at Knott's was removed after Cedar Point's collapsed. And the one at SFMM still operates under the name Thrill Shot...and I believe SFGAdv. has one as well.
Cedar Point's tribute to a (literally) fallen ride at HalloWeekends.
The one at SFMM hasn't been open for months, but will re-open very soon if it hasn't already. Frontier City also has one, and their's is actually free, no extra charge.
after the one at CP expierienced a Vortex Shear Fracture (sending one tower to the ground during the off season which S&S says if CP's fault for removing the cables), they were all removed exept for SFMM's which was modifyed). The current ones are significantly shorter than the original.
Also at this time some issue has shut them all down, but they all seem to be getting ready to reopen (being reassembled)
