Fuego y Agua Race?

My main race of 2013 is the Umstead 100 miler on April 6-7.  That should be enough for a "regular old ultra runner."  But I keep getting drawn toward Nicaragua and the Fuego y Agua ultramarathon.  If one of my buffalo friends officially signs up, I'll join them in February running up and down a volcano in the middle of a big lake in southern Nicaragua. Sounds like a nice winter getaway.

Heck, if no one else that I know goes, I may just go solo.

Fuego!
          Agua!
                   Fire!
                          Water!
