Half a Block Traditional Cache

A carry on of my 'Half" series to join up with my "Kelly's Walk" series. The cache is on a public foot path that follows the route of the Grand Union Canal in the tunnel below. In days of old this is the path that the horses were led along while the canal boats were "walked" through the tunnel. This is a small cache so please bring your own writing implement. 

Look for the small concrete block on the side of the path. As with the rest of the series this is a high muggle area of ramblers and dog walkers so please take care when looking for the cache
