Geocache Description:

Not at the published coordinates which are for a free car park. A puzzle/multi-cache hybrid. First decode the text to provide a set of questions. Next visit Cobham to answer to those questions and, finally, locate the cache. Cobham is not a large town so it shouldn't take too long to track down the information you require.

Stage 1: Decode the following Vigenère encoded text by finding the name of the dragon shown in the background picture.

To make things easier you can find an online decoder here. To use the decoder, click all of the clear buttons and then copy and paste the blue text above into the Input box. Type the name of the dragon into the Key box and click on the decode button. Simples!

Stage 2: Answer the questions.
If the answer to a question is not explicitly numeric use the following guidelines:

  • If the question asks for a letter, convert that letter to a number using A=1, B=2, C=3 etc.
  • If the question asks for a word, count the number of letters in that word.
BLUE PLAQUES
Q1=A Q2=B Q3=C Q4=D Q5=E
ODDITIES
Q6=F Q7=G Q8=H Q9=I Q10=J
The checksum of all your answers, A to K, is 66.

Stage 3: Find the cache.

The cache can be found at N 51 AB.CDE W 000 FG.HI(J-K).

Please note the cache was relocated on the 30/07/2023. If you have researched the answers prior to this date you will need to resolve/recalculate the coordinates. Most of the locations remain unchanged from the original. The questions were last revised on 30/07/2023.



This cache is a sister cache to another puzzle/multi that I set around the same time. Many of the locations are the same so why not try them together?

The original cache container and some of its initial contents were recycled with the kind permission of the previous owners. See GC1HW9Q for its original home. Sadly this container has long since gone.
