After having the 'Rainbows' in our area for a gathering, I can totally see where this town is coming from. I am not even a bit convinced that these two were willing to 'pay' for anything. The theft rate in our area went up considerably and to top it off, the group actually got insulted when they were removed from businesses. Most businesses today don't have a huge profit margin, so to have a 'wave' of people come through town stealing whatever they can get their hands on is not a good thing. Also they are not too kind to the environment as they left the area they 'celebrated' in a huge mess. So six months, so what, they will be out in time for the next gathering.
You hit it on the head.
I have friends who have attended the Rainbow Gatherings (I have some pretty flakey friends), and they tell that same story from the inside, too.
Can you wait til they actually steal something??
