I oftentimes search for event tips that are unique and out of the box. I think that Youtube is a terrific source for these kinds of tips. All you have to do is go to Youtube and do a search for "birthday party ideas" and you are going to find several hours worth of clips with numerous very good ideas. The problem is, who has time to watch them all? So I am on a continuous mission to collect some notes to save me and also hopefully other people some time.
