Hey there,
I was looking for the link to the Northern California Gathering
webpage and I thought some other folks might need to see it again too!

This should be a terrific event! These folks are pioneers of
letterboxing in the San Francisco Bay area. Before they arrived on
the scene, the only letterboxes planted around there were by tourists
passing through.
