WoW so smokers, pot smokers, kids runnin around adults partyin, and people talkin at a festival is now a problem? Maybe you folks were at a different festival than me, or maybe you wish you were at a different festival altogether. Keep hopin for more rules and regulations and you just may get them. My guess is you would just find something else to complain about.
I'm a laid back kind of person. I know that there will be people moving and a general background noise at any festival. I don't mind people walking through my shade tent area. That's why I like the EZ-up style so people can get back and forth to their space. I had lots of kids walk or even run through my tent and I didn't mind, heck a few of them even said "excuse me". I don't mind people dancing.
But I do mind when a few people blatantly ruin the festival experience for all others around them. "It's a festival" is no excuse to be rude.
