So, about the clock- I don't think people really realize what's up with it.
Over the last 5-ish years the park has gone in during the offseason and done a minor touch-up on it each and every year. From what I've been told, it's a maintenance nightmare but, typically, some work gets done- at least enough to make most of it run. The exception to this was 2013 when, reportedly, the park simply didn't have the time and/or money to do even the bare minimum- this is why it essentially didn't function at all last year. While it's nice to see that it did get its yearly off-season maintenance again this year, this really isn't out of character- 2013 was simply an exception to the rule.
To be honest, at the end of the day, it sounds like the clock needs a true full renovation. During the AB days the park could spend untold amounts of money throughout the season to keep the incredibly complex mechanical system that drives it running but, now, from what I understand, it's simply not financially feasible. While I'm always glad to see it running for a month or two after the park first opens each season, it's always just a temporary band-aid. Year after year it ends up deteriorating back to being essentially nonfunctional once again.
I love the use of an authentic, fully mechanical system just as much as the next guy, but at the end of the day, no one sees it and I'd much rather simply see the thing consistently functional- if that means gutting the internals and replacing it with a new computer-controlled system, I'm all for it. Theoretically, if done right, everything could/should look the same to the guests and, well, that's what matters.
