---(2010-08-05, 12:22:05)---(DNF)---
After our DNF in May we returned to try again. This time, with the benefit of some advice from sandvika and Amberel, we had a much smaller area and a definite object to search. The object has changed since May and would have been much easier to search then
. We had a good look but if the cache is still there then we can't find it. As it hasn't been found for almost two years perhaps it needs checking and/or replacing?
