Well, "Lewis Carroll" was his pen name, anyway. He was really the Revd Charles Lutwidge Dodgson. And he is one of many people buried at The Mount Cemetery in Guildford. You can find his grave just next to the chapel, signposted for the visitors.
Another interesting feature at the south end of cemetery is "Booker's Tower". This was built in 1839 in memory of the sons of Charles Booker (then mayor of Guildford), "to perpetuate his name after fate had robbed him of his two sons". It's not open to the public, but it's worth a look at from the outside.
The cemetery is a lovely, peaceful place. Enjoy looking at LC's grave and Booker's Tower, but please be considerate to other people visiting.
The co-ordinates given take you to the gates of the cemetery. Parking is available in 2-hour bays further up The Mount, however it could be limited. Please be considerate to the local residents. Make sure that it IS a 2-hour bay, there are some that are resident-only. Alternatively, take a break from shopping in Guildford town centre, and walk up the hill! It's good exercise for you.
All the info needed to complete this offset cache is found on the blue sign located on the right a few metres inside the gates. The cache is not located in the cemetery, and the whole can be completed when the cemetery is closed (providing your eyesight is okay enough to read the sign from outside the gates). However, I would not suggest attempting the cache when it is dark.
You're looking for a black 35mm container, containing a log only. It's located nearby, but where? Well, the blue sign discussed above displays the cemetery opening times and other information. There are four lines of text at the bottom of the sign, smaller than the rest. Within these four lines, deduce the following four values:
A = Number of letter 'O's in the third word of the fourth line.
B = Number of letter 'I's in the first two lines.
C = Position in alphabet of the fourth letter in the first word of the third line.
D = Number of letter 'E's in the second line.
Then the cache can be found at: N51 13.8AB W0 34.CD3. Easy! Bring a pen to sign the log, and please replace as found.
A special thanks to mashworth, who confirmed the co-ordinates for me, as I don't use a GPS. However, I told him he couldn't have the official FTF...
...which went to Prosniper, within 24 hours of publication. Well done!
