I have clues to a new letterbox in Sunol regional wilderness,
on my website at http://www.mapsurfer.com/boxes/box41.html .
This box has an orienteering theme.

There is a twist to the usual letterboxing rules. Since the original
stamp is lame, visitors are encouraged to carve their own and replace
the one that is there. There is one rule -- the new stamp must contain
the word "Sunol" somehow in the image. This step, obviously, is optional.

For those who may find this information useful, this is the 16th
state with one of my boxes.

Cheers
