Could Cedar Fair file a lawsuit on Viacom for inheriting Son of Beast in the first place? Even if you couldn't, at least have Viacom pay for whatever CF wants to do with it, whether it'd be to refurbish it with retracking and new trains, or to destroy it.
One could also question the expertice of inspectors from the Ohio Department of Agriculture for saying it was safe to operate, and now has been proven otherwise. I honestly think even the most seasoned enthusiast with knowledge of Son of Beast's flaws won't go near it.
