I think Six Flags shouldn't waste the money, but also thinking about another cool idea.
We retrofitted Bizarro with wing-carts, and lengthened the catwalks. We also had two wing carts and two of the regular floor less carts. We could put another queue on another part of the ride. One queue for wing, one for floorless!
I also think we should do the same with Green Lantern. Putting some floor less carts on that would really be awesome, with that straight drop!
I understand that this will never come to fruition, but it seems like a cool idea to me.
