I beg to differ... if you check out the definition of a cache, you just described it, pre-positioned items for use at a specifically defined point in time (even if that point is defined by "when I need it").
Caching was a militery thing 'til the survivalists got hold of it, then, suddenly, a cache wasn't a cache unless it was a hole in the ground filled with a bombproof container.
Also, distance hikers and bikers used caches on pre-planned trips for years (maybe they still do?) before it became the signature of the survivalist movement. At given points along established trails (Skyline Drive, along the Blue Ridge, for example) they'd have supplies left (often at Ranger stations or established businesses) to top off their supplies and gear during their trip.
As was said about the S word... cache maybe good, not neccessarily bad ... c'mon folks, yer chokin' on the P.C. pablum, spit it out for a while <img src="/images/graemlins/shocked.gif" alt="" /> <img src="/images/graemlins/blush.gif" alt="" /> <img src="/images/graemlins/wink.gif" alt="" />
