Tiny post office in a tree hole

The spirit of Boo Radley lives on in the hole of a tree growing in the hills above Berkeley, CA. Gareth says, "Lea Redmond, of Leaf Cutter Design and the World's Smallest Postal Service, did a photo illustration for Borg Like Me. She created a Lilliputian post office in a tree hole in the Berkeley Hills. She left it set up and it's still there 7 months later! People have not destroyed it; they've been ADDING to it and leaving mail for the fairies (it IS a post office, after all)."
