For those of you who don't know, the infamous local cacher RPieperCO has a deep secret love for football. It's so secret that we're not even sure if he knows about it.
His favorite football player is a former NFL running back named Billy Sims. Now Billy only played professional football for five years and, though he was the first draft pick in 1980, he had the misfortune of playing for the Detroit Lions. Injuries shortened his career, but Billy continued to make a name for himself after he hung up his pads.
This cache is placed near an establishment that honors Mr. Sims. The employees of said "shrine" are aware that there's a geocache here but they don't know its exact location. The difficulty and terrain ratings may be high for some of you, but for others it should be just right.
Good luck!
