A fun trip from bottom to top. Find the micro, then the macro. Be gentle with the equipment.
Cache contents are numerous and crazy.
Beware, there are CLIFFS about, so look after geokids, etc.
Those with acrophobia need not apply (again)
Those with rustophobia, watch out!
EDIT: Years down the track, and the ladder's no more, you'll now go around - that's a bit of a chore!
