[Az-Geocaching] Digging holes

Fri Sep 14 00:47:42 MST 2007

OH YEAH!!!! that's bringing back some memories.  I don't know if the one I
used when I was a teenager was store bought one or just something someone
fashioned at the ranch... but I remember beating the crap out of the rocky
dirt of the Springerville volcanic field.  They also come in handy for
prying out large boulders from the ground.  Rototillers don't do so well
with rocks bigger than golf balls hidden in the ground.... how ever teenage
grandsons with a tamper bar CAN plow where the rototillers can't.
