Yeah, I had the chance to ride Mantis with ERT at Coastermania too, but since I had already been on it 4x that day (2x when it first opened-the first train out, up front, and the 4th train out). The up side to this story is that these 2 rides were the best experiences I've ever had on ole Maggy.(in the ejector too)
I was just sort of alarmed at the Maggy count, because it said 1 up there, I thought that was your yearly count!
