Noice!
Like to find out more about boomerangs? I'd like to use this opportunity to direct you to the United States Boomerang Association (USBA.org) It is a great introduction to this ancient (and yet crazily modern) sport. Membership is free! How far can they go? How long can one stay in the air? I think you may be surprised.

This extended car warranty follow-up is really getting out of hand.

I highly recommend Vectorpark's other game "Windowsill." The best $2 I ever spent. Even though both of my kids have discovered how to solve the puzzles in each level, it is a game they keep coming back to because it is highly imaginative and just flat-out beautiful. "Levers" is another free game that is both challenging and entertaining. Heck, anything they do is worth fiddling with.
