I have figured it out. They are doing a Bizarro treatment to Millennium Force. The lightning will be in both tunnels where riders will be painfully shocked with 30,000 volts. No longer will it be called Millennium Force-less!
To "get" Magnum you kind of had to be there 20 years ago. There was nothing like it that I had ever been on. At 10 years old that thing scared me to death. I had ridden other costers at KI, BGE, GL, and WDW. That 200 foot tall hill was the tallest in the world it did make you "gasp"
