My husband and I just planted a letterbox in GG park ("leafy" the
letterbox). We tried to make the clue/map easy. Let me know if
anyone has troubled hunting...

1. Anglers' Lodge Casting Pools (go there)
2. Find the aquaduct trail, between the doghouse and "horner's
corner" (hint: west side of pools, aquaduct starts about 10/15 feet
down trail, and trail follows it for most part)
3. Mosey down the trail, past and around the giant eucalyptus, to the
clearing where a fallen tree lies to your right (hint: this is about
90 paces/steps from the trail's start at the pool's edge)
4. At the clearing, turn to your left, following a trail southward.
Go about 40 paces and vere left onto the trail leading up over a
small hill - groundswell, i'd call it.
5. Almost there... at the top of the mount there is a tree on the
very right edge of the trail. Pass it. The next tree on the very
right edge of the trail is home to "leafy" letterbox.
6. At the bottom of the tree trunk (a very tall one) is a hole.
Stick your arm in and dig out a little dirt. Grab the letterbox, too.

We are going to add a few tiny swapping items today, and right now
there's just the box's stamp, inkpad and small notebook. It's a
small box. Swap anything except for the stamp, inkpad and notebook
(someone took the stamp from the last box we found, please don't take
ours! Besides, I cut my finger making it so it'll bring bad luck if
you do.)
