This is a very traditional cache--tall blue rubbermaid-like
container in a black bag.
Bring the kids along (even the very young ones) on this hunt and
then spend some time hiking throughout the park. Have them hunt for
green snakes, huge cicadas, butterflies and moths of all colors
(yep, even in late November), armadillos hiding in the brush, and
show them the holes in the ground dug by armadillos and wild pigs.
I saw all of this and more on my little jaunt with my parents.
