It is not generational. It is not newbies. It is everyone.
It may be that there are more issues today, but that is simply because there are more people camping. I have seen many examples of older campers (both in age and experience) with a "I'll do what I want and be d@mmed about others" attitude.
Most of the list is about partying. That does tend to be a younger person violation. But some issues are ageless - firewood, golf carts, illmannered kids and dog, etc.
The more we keep trying to blame all the issues on one or two categories, the more the rest of the problem campers get away with being idiots.
