Historia vero testis temporum, lux veritatis, vita memoriae, magistra vitae.
There is a Wiltshire cacher who is very interested in milestones (real ones, not statistical 'milestones') and he labels his milestone caches Z to A - (something or other). Milestones also appeal to me and I have found a couple of his Z to A caches. They have no bearing on this cache, but they may be found here: Z to A search. Anyway, in case you were wondering, that's some of the rationale for the odd name. I didn't know it at the time, but my research for this cache began about four and a half years ago.
