i remember when anaconda was being built. i went to the park with a friend, and at the time all that was there was the lift hill and the two ensuing loops. we rode Rebel Yell to get a better look, and i can still remember my friend yelling "holy crap, look, it goes UNDER the lake!"
i also remember riding it when it first opened. it must have been a saturday, because the line extended all the way through the congo back almost to Avalanche's exit. i also remember the ride being advertised as having "6 loops" and even as a kid, i thought this was BS once i saw that two of the "loops" were that lame butterfly element, and weren't even close to being legit inversions.
originally, the MCBR did not slow the train nearly as much as it does today, and i think this actually made the ride a wee bit smoother. don't get me wrong -- it was still a rough Arrow looper, but seems to me like slowing it down to a near-stop causes even more sideways banging around as it navigates those sloppy turns.
i've said it before, but if they removed those two crappy turns after the MCBR (and loosened up the brakes on the MCBR as well), anaconda would be one of the best Arrows around.
