Here are two vidcaps from vids one and two. With up to 200 women participating, thats a lot of covered boobs. YOu will also find lots of tantalizing footage of topless women lying on their stomachs.
Also, the Barker600alive official site is linked to below. I have not seen the official vid yet, unless it is one of the ones I posted already.
