Yea, instead of a multi I could make it a 3-4 or 5 "series" cache and make people collect info from each cache to form the cords to the final cache site, and consider that leg two of the final cache: ie 1 reg cache, 2 reg cache, 3 reg cache, 4 a 2 part multi, or mystery cache with part 2 being the final cache at the final location. Does anyone know of any others like this?
