I routinely look for event approaches which are out of the ordinary and out of the box. I find that Youtube is normally a terrific resource of these ideas. All you will have to do is head to Youtube and do a search for "event tips" and you can see hours and hours worth of videos with lots of fabulous ideas. The issue is, who exactly has the time to watch them all? Thus I am on a constant quest to collect some notes so as to save me and also perhaps others some time.
