Well considering the BTMRR was closed on 8/25 for an extended rehab.. I think its safe to say that it wasn't affected.
We drove the train around BTMRR on 8/29 and noticed that the track was up, caution tape all around and some construction workers near the cave...
And honestly, accidents happen. I remember a few tragic accidents at my local Six Flags.. yes they were 20 years ago, but it still happened. No, I am not afraid to ride Rolling Thunder or other coasters.
Unfortunately, sometimes the deaths/accidents occur because of the patrons on the ride. Some want to stand up on the lift hill of the coaster, and physically remove the restraints. Some people try to exit the log on Splash Mountain.. even after repeated warnings not to do so. Yes, this is tragic, but some people decided to go against warnings and unfortunately, injur or kill themselves in the process.
When a park has an accident, they tend to be overcautious, and that attraction, gets double/tripled checked and more spot checks.. believe it or not, that ride/attraction is even more safe than it was before.
You don't notice it, but there are safety checks in the rides.. both attendents check all the restraints before launching RnR.. you don't really notice it due to the other things going on, but it is done.. (that is because of clever cue lines!)
So in closing, don't be afraid. The safety checks will still occur ( more of them), and all that.
