Do whatever you want to do, in my humble op, only remember that not everybody finds it hilarious. I recall a fun-loving bunch driving through Houx last year, spraying water at everyone they passed - fairly light-hearted, but when video cameras, personal belongings, sleeping bags and even beautifully grilled steaks got in the firing line it got a bit ugly. Ugly to the extent that a gallon bucket of water and a few half-full beer cans got hurled into the car from some of the more pissed-off victims. I'd venture that a few teeth would have been knocked out, had the driver not realised the gravity of the situation and stepped on it.
Like everything else, it pays to weigh-up the situation before letting fly.
