A Mad Scientist

My friend, Carlos, and I decided that we must search for the Yeti two years ago.  On a climbing tour in South America our guide told us all about this mysterious creature, and we have been mesmerized since.  Everyday we researched.  Unfortunately, hardly anyone knows anything about the Yeti.  In fact, there is only one grainy photo and a massive footprint that provide any proof of its existence.  Our contact in Nepal (home of the Yeti) is a Yeti expert, but even he is unsure if we will find the Yeti.  Nonetheless, we intend to be the first to discover and reveal the Yeti to the world.
