I am a huge supporter of flat rides, as it seems most of us are, but I do wonder if SFMM even needs them. It's true, they're great complimentary attractions, but when you have a park with enough roller coasters to round out a day with leftovers to spare, how many people are going to schedule in time for a flat? I go on the flats at Knott's because I have to in order to stay for more than a few hours, SFMM doesn't have that problem.
Also, to bring up a topic from a few pages ago, do you folks think the structure is wide enough to support two different tracks? Clearance between the two tracks isn't much of an issue when they never stray away from each other, their clearance envelope simply overlaps each other's, but if you have one track raising and one falling, suddenly where there used to be open space you have a bunch of supports. I'm not saying its impossible, I'm sure it is, but I'm also not sure it's as simple as we think it is...
