The history and the stories told where great. However the guide walks really fast and jaywalks making it hard to keep up and caused the group to become broken up. The extended was awful, not for the stories again but for the route taken. There was a literally drug needle on the ground, empty liquor bottles, a homeless man came over and asked for a light and then a lady who was on something quickly approached the group then turned and wondered if into the rain. The stories were cool, but for everything else I wouldn't do it again. The guide was so far up in the front I don't think he even realised half of what was going on. But for someone who recently had foot surgery and can walk but not speed walk I was a little freaked out bringing up the tailend of the group by myself in the dodgey part.
