On the back of the sign is a label with a yellow number ABCDEF.
The cache may be found at N 51 17.(A+E)(B+C)(E-F) W 000 37.(C)(B)(A+D).
The sign has been changed and so the formula completely revised to cope. 2020-08-31.
Please only log a find if you have signed the log. If you haven't, try adding a "write note" instead. Thanks.
