AS for your poll question, I voted NO. Many of the gags described in that book are still viable. Many of the promotional ideas are getting outdated. Empiressnightshade already found out that getting a PSA is a lot harder than just calling up your local Radio Station and asking for one. Most cities also have strict guidlines on selling food for extra revenue.
"How to Run..." is STILL the best known book for haunters out there, and I still suggest that everyone have a copy or at least read through it. But there are better ones available now. Kel Allen - who posts here - has a very good one. As for building projects, there are LOTS of websites out there that will tell you how to build bigger and better props on a budget.
