Many caches are designed to bring you to a beautiful place and I assure you this will (unfortunately not physically). Madame George is a song on Astral Weeks and in the song he references Fitzroy Avenue. If you get a chance to listen to the song or the album, before you log the cache, please comment on the music.
The cache is a magnetic 5ml container. The cache attaches to the pole, not the sign. The magnet is very strong: I suggest you keep it away from your electronic devices and your bank cards. Congratulations ED999 another FTF for you.
