The posted co-ordinates of this cache listing will take you to: Milliways, better known as the Restaurant at the End of the Universe. It is a five star restaurant situated at the end of time and matter. Its main attraction is allowing diners to view a gnaB giB before desserts are served. Please park your interstellar cache mobile at the posted co-ordinates.
Depending on the spatial time period you warp out of you may be disappointed to find only the remains of the fabled restaurant. Please do not dispair. Do not approach or search any abandoned structures, they are on private property. Aurthur Dent and Ford Perfect have left a galactic space beacon (a chirp enabled GPS is required) which will give you the coordinates to your final destination where the gnaB giB can be best viewed from. At your final destination You will find a small tethered and locked container which contains a guest log and small selection of souvenirs.
Your journey to the final destination will be an arduous hike but if you travel by inter-galactic cache mobile your warp drive should get you there in approximately 0.000234 parsecs.
Please remember to bring your towel and a pencil to sign the log. Of course the correct babel fish are highly recommended. Safe travels as you traverse the galaxy 😊👍.
