Lol is the sky really falling? Could Dragster be closed forever? Maybe. Is it ExTrEmElY NaIvE to think it will open again? No. Far from it.
Stop overreacting to what was an unforeseen freak accident. It was terrible, but let's not blow it out of proportion.
Before someone flips shit about the queue placement, or makes claims of recklessness, how many other roller coasters have high speed passes close enough where a dislodged part of a train can kill someone? What on Earth are we going to do with Gatekeeper? Cork Screw is ffff'd. Tear it down. Steel Vengeance isn't just as likely?
How many times have each and every one of us stood as close to a roller coaster as a pathway would allow, to "oooh and ahhh" at it as a train sped by? Has it never crossed anyone's mind that maybe... just maybe... there's a chance something could dislodge from the train and injure someone? Any roller coaster traveling over, or near any path has a similar potential. You're going to have to tear down the whole industry to rid guests of that danger.
If CP changes the queue location, it's strictly a smoke-in-mirrors act.
