"Then finally our archer opted for a slightly different tactic..."

This comes from a cache entitled "Psycho Urban Cache #13 - Impossible! Give Up Now!", which is located atop a 140' stone pylon in the middle of the Potomac river (formerly it supported a bridge, which is now gone). The technique of choice for retrieving this geocache seems to be to shoot an arrow trailing string up and over the pylon, then haul up a climbing rope and ascend that. It's pretty ridiculous.

As long as I'm on the subject of weird things overheard at geocaching.com, here is one that comes from a log on a cache I hid:

"...this one had something for the whole family, provided the family included electrical engineers and people wearing long pants."
