The third in the Charlie Series located in the wonderful Chew Valley, south of Bristol.
A busy junction, with lots of muggles around, so some discretion will be required.
You are looking for a small tin, about 50mm x 30mm.
EDIT AND UPDATE After the previous cache was stolen, we have replaced it with a smaller microcache which will be a little harder to find. That means you will now need to bring a pencil to sign the log. It is in the same location and the clue will have equal relevance. When you find it, please return it in the same condition and put it back in the same place so that others can enjoy it.
