Consider all the places you'd advertise if only you could get permission, or had a healthy disregard for the powers that be. If your brand lives by its own set of rules, and you don't mind taking a few chances, you've got some truly awesome options that others can't access. You'll escape the clutter of conventional venues, distinguishing yourself from the crowd. And if you do it justice, you'll get plenty of free press. Best of all, you will become a bright blip on the consumer's radar screen, which is ultimately what it's all about.
