thank you!! regardless of whether it's all connected by concrete or not doesn't mean it isn't the same thing. the supports at the bottom of the lift hill look the same on numerous B&M's (LZ/Time Machine, Diamondback, Behemoth, Goliath(SFOG & La Ronde), ect.). Though not all do, it gives sort of a clue as to what the footer at carowinds is for.
It probably has to do with how close the ride starts to the ground also.
I'm not saying it's 100% a B&M.... just helping out and giving a bit of wishful thinking.
(ps. Most of the coasters with that type of support are hypers ) lol
