A traditional letterbox hybrid. The cache is not at the posted coordinates, but you will need to go there first.
This is a Victorian Post Box, set into the wall of a public house.
You need the date on the post box - ab/cd/efgh - this is immediately to the right of the postbox number (YO7 19D).
Use the numbers from the date to calculate the distance and bearing from the post box to the cache.
distance = (d) (e+g+h) (c) metres
bearing = (g) (f) (a+d+h) degrees
checksum = (distance+bearing) = 487
The cache contains a stamp, which MUST remain in the cache. The cache is a small container, large enough for small trackables. You must sign the paper log in the cache to be able to log online as 'Found'. I reserve the right to delete your online log if you haven't signed the paper log in the cache.
Another cache in a National Numbered Series of Letterbox Hybrid caches, placed to mark one of a diminishing number of post boxes placed in Queen Victoria’s reign and still in use for regular collections by Royal Mail.
If you know of an eligible post box and would like to add to this series, please apply to Team Hippo for a series number, giving the following:
- Location as in place name (and street if applicable)
- Location in Lat Long format (DD MM.MMM)
- Postbox number
Please note that featured post boxes should comply with the guidelines above. Caches should be Letterbox Hybrid type (and therefore contain a LB stamp), whether placed at the published co-ords, or a simple offset multi, or multi-stage multi, or more of a puzzle style format.
