"Plan on bringing Number 5 back in service once again"
Purely conjecture but what if #5 is referring to the fact that SOB was (un-officially) the 5th coaster the park built if you take into consideration that Racer is One of Two coasters. IOW...
Racer #1-#2
Scooby Doo #3 (I know, old school name)
Beast #4
SOB #5
Just throwing it out there, but could we be seeing an SOB ground-up RMC?
