Tramping through the woods.
Bug bites.
Where is that d%#* box?


My compass is whacked.
What does
Declination mean?


Serendipity:
This box
Has a hitchhiker!


Crushed! This box stamp's been
Swapped by
A geocacher.


Family boxing.
Three kids.
Who ate all the snacks?


I am exhausted.
Seven
Hundred yards straight up.


The Pakrat

I like them. Thanks for sharing.

The trail winds around.
Box Found!
Now on to the next.

I can not find it.
Calm down.
I think I see it!
