Austin Crecelius took his girlfriend, Allison Boyle, on The Voyage, a huge wooden roller coaster at the Holiday World amusement park in Santa Claus, Indiana. As they neared the top of an incline, Crecelius turned to Boyle and said:
At one point in time, you had mentioned to me that life is like a roller coaster. And it's got its ups and downs, it's got its twists and turns, and it even throws you for a loop sometimes. And you can go by yourself, but it's a lot more fun to go along with another person. So I wanted to ask you if you wanted to be my roller coaster buddy. Allison, will you marry me?
Boyle said yes! Then, immediately, the roller coaster plunged down.
What would have happened if he had dropped the ring? Crecelius was prepared: the ring that he slipped on her finger was fake. He gave Boyle the real one once the ride was over.
