I took the cog once and took a van the MWN road several times. Didn't want to torch my brakes..lol. But the Cog? Yeesh. I'm sure it's fine now, but the time I went up was terrifying. A piston broke on the way down, and it was manual brakes the whole way down. There was a legit feeling that we could just be a runaway train. It was to the point that the workers were ready to jump and my parents put us next to the windows in case we were going, so they could throw us out. I'm not kidding. I was only in second grade, but I remember the look on my parents face. That said, I would definitely do the cog again.
