In 2006-2008 the crusties formed a gauntlet between Cole and Clayton on Haight. They were rude and aggressive and always had at least one rottweiler or pit bull. The locals and tourists could not stand them and the only reason they lasted as long as they did was because they were white. Eventually everyone got too fed up which is why the no sit laws were passed.
I vividly recall walking west on Haight to The Alembic in the summer of '07...it felt like something out of Mad Max or a post-apocalyptic zombie movie.
