andrewmb: I went to check on the reported DNF and HarrisonPhoenix was right, the cache is not there. This is the third time that the cache container has gone missing; the most recent one only lasted a month and the one before that 10 months (although it had to be replaced mid-way due to the contents getting damp).
I looked for a more robust hiding place, but couldn't see one that would be suitable. I have therefore decided to archive this cache rather than place another container that will probably just go missing in a couple of months.
The cache has had a good run for just over 3 years with exactly 100 logged finds so I thank all of the visitors and apologise to all those who would have visited had I replaced it rather than archived it.
