The Grand Union Canal links Birmingham to London with a waterway
which is 145 miles long and contains 166 locks. This cache is one
of a series to be found along or close to the
Hertfordshire/Buckinghamshire stretch of the canal.
You are looking for a small cammoed tupperware container. As
with all these canal caches, please take care near the water,
especially if caching with kids, make sure that no muggles see you
with the cache and please do a good re-hiding job. Thanks.
