I love roller coasters.  The Voyage at Holiday World.  The Beast at King's Island.  Desperado in Primm, Nevada.  And I would be all over this!  Have you seen the Sommerrodelbahn?  It's an alpine coaster in Mieders, Austria that has absolutely NO brakes.  It begins at the top of a mountain and doesn't end until it reaches the bottom . . . nearly 4 minutes after the ride begins.   Look at this thing!

So, let's have it.  What's your answer?  Are you game?
