For those who don't know, every coaster is thoroughly inspected every single day before a ride opens, and is evaluated with a comprehensive checklist.
It's odd that anything could have happened to Hurler's structure to cause such severe damage, as the Theme Park Review member has reported. Hurler is by far the park's youngest wooden coaster, its footprint is on completely level ground, and there are no large trees nearby. Plus, Kings Dominion might not have the best operations, but there's no way their maintenance is so bad that a major coaster is considered unsafe due to negligence.
Even if something were wrong with the coaster, it's doubtful that the damage would be so extreme it couldn't be fixed for an entire season. More concerning is that zero work has been completed to fix this supposed damage. So, if Hurler really does have a serious safety issue, it's obvious that fixing it isn't one of the park's priorities.
Kings Dominion isn't one of Cedar Fair's high-up parks, but Cedar Fair is still a multi-billion dollar company with a high profile. They don't invest the same cash into their lower-down parks, but I can't imagine Cedar Fair giving Kings Dominion such a big middle finger that they refuse them the funds to fix a broken ride... not just some kiddie ride or a measly flat- a huge, highly visible wooden coaster that's one of just three coasters on its half of the park. Surely if KD wanted to fix Hurler quickly, CF already would have made the investment.
Like Matthew said, it's very possible that KD just took the loss and decided it wasn't even worth the cash to get Hurler running, given its horrendous reputation and dismal popularity. Or, at the very least, they decided not to rush the funding for a refurbishment and figured reconstruction could wait until next season.
