A couple of days later, I was able to hit a few geocaches in the Yucca Valley and Joshua Tree area; most seemed to be placed simply to place a cache, but one was at the Joshua Tree Inn, which has a bit of interesting history to go with it (click here).
A day before departing to come back to Okinawa, I had the pleasure of accompanying my father on his first geocaching experience. He found his first cache after a brief search, and he's now a genuine geocacher.
Here's a few pictures from the Park:
