Nearby to the existing Fisherman's Tail Cache and in a similar vein. I'm not quite sure whether this is what most engineer's really dream of, but, as they say, whatever floats your boat - and no doubt there are some high brow mathematics and design to that?
I would suggest that to avoid being overlooked this cache is tackled outside normal office working hours. As this is such a busy location the size of the cache is very small. Please only use initials to log your visit. Thankyou. Less able persons may need some small assistance to make the grab, however the area in general is very accessible, and, outside office hours, you can park with 10 metres.
