Yes. The queue rails at SFMM. Most of them are painted (as in not plain stainless steel rails), and what happens to that paint? People take coins, keys, and what have you, and scratch things in to them. It looks like crap. This wouldn't be a problem if they would get repainted frequently, but that's not the case. Cedar Point has a better alternative: don't paint them in the first place. And no, SFMM isn't the only park in the universe that has to deal with vandalism, but due to it's geographic location (and subsequent demographics that the park attracts), it gets more people that have a propensity to vandalize things than a park in, say, the Midwest (see again: CP). In summation, if a park wants to use materials that are highly susceptible to vandalism, that's fine. But they need to be more on top of their game in the upkeep department.
I dont think I have ever been to a park and not seen this, I personally dont think it has a lot to do with their demographic.
