Yup, this scam is still going on, last year sometime I was offered speakers out of a white van in berkeley. They'd gotten smart and were using chicks to get guys attention... I just said no thanks and keep walking, as I'd read about it before. I think the main idea is to get college age guys who can't afford good speakers but want to have big speakers to impress their friends and don't know any better. I figure they're about the same quality as the massive speakers they sell on ubid.com for $9 plus $120 shipping.
