boomerang... what's happening?

In the cheesy romantic comedy "Little Black Book", they are used as a symbol: "The boomerangs, you know the kind. You throw them out there into the world... and they always come back to you". Maybe you've never seen them before or maybe you have a diverse collection; you may not know that they originated in Australia more than ten thousand years ago. I may have not mentioned that native peoples called Aborigines lived in Australia way before the colonization and their innovations have proved to be quite successful, including the boomerang. This invention is also known as the first heavier than air flying machine humans have ever made (as far as we know). Not only was it used to hunt wild kangaroos, but it was also used for communication.
Presently, they are continuing the boomerang traditions through international competitions every other year. In honor of its origin, they have an Aussie Round (which many consider "the ultimate test of skills"). Apparently, last years tournament was held in Tucson, Arizona. (http://www.absoluteastronomy.com/topics/Boomerang is the perfect site if you are looking for more techniques or facts). Quite honestly, I have to wonder why this event wasn't publicized or advertised as well as it should have been. Boomerangs will grow into a major sport one day. Or maybe it's best just to start a boomerang club myself.
