I’m from the area and it’s most likely spoiled rich brats who decided to go on a vandalism spree after getting drunk off their parent’s booze.
I sure hope they're caught and directed to reimburse the county, and provide some serious sweat equity. Being from the neighboring county, I agree that it was most likely perpetrated by spoiled rich kids. More typically they trash a private residence in the course of an unsupervised party, but this kind of behavior pops up from time to time.
