I have finally got my "Bigfoot-Be-Gone" patented. I'm ready to start moving towards marketing my revolutionary device. For a mere cost of $99.99-- plus shipping. You, and your family, can drive the highways with total confidence. That your vehicle will never be involved in a collision with a Bigfoot. This tiny thumb size device is secured on to your vehicle's hood with a special magnet. It omits a signal in a frequency that can only be heard by a Bigfoot. The transmission is extremely loud, and can be heard by a Bigfoot 2 miles away. It shouts out things like, " Hay stupid, get your big butt on across the road." And, "move it, or lose it--big fellow." By the time your vehicle reaches the Bigfoot crossing, you wont even know a Bigfoot was ever there.  But wait, hold on-- I'm not through yet. Each additional Bigfoot-Be-Gone is only $59.99.  Make sure all your vehicles is safely secured. That is not all, you will receive and money back guarantee which states-- If you can prove your vehicle has collided with a Bigfoot, you will receive a entire refund on your original purchase. DON'T MISS OUT on this once in a lifetime offer. Soon I will list where you can buy your own peace of mind. 
PS--if not for yourself. Buy one to ensure that you don't wipe out a entire family of Bigfoots. They move more slowly tending their offspring.

Shouldn't it be "wipe out a entire family of Bigfeet"? Just sayin'.
