Rodney Anonymous has been posting a multi-chapter visitors' guide to Philadelphia for the benefit of those attending the Dave Blood memorial concerts the Dead Milkmen will be presenting November 21 and 22. But regardless of your reasons for visiting, it's a darned good insider's guide. Part the First, Part the Second and Part the Third.
Philly's City Paper had a cover story previewing the shows.
