Cache is not at the posted coordinates nor is it the beginning spot for the adventure lab. It is, however, a good spot to tell your Uncle Rico about your online girlfriend, LaFawnduh while also making plans to sell plastic bowls. Ok, the restaurant in the movie was actually in Richmond, Utah about 15 miles south of here but they are both named the same.
This cache is the bonus cache for the Napoleon Dynamite Adventure Lab. The coords for this cache will be in the journal entry for the 5th location when you have finished the lab.
