SAN FRANCISCO (AP) — A tiny tree door has appeared in San Francisco’s Golden Gate Park after another one was removed because it violated city code.

The San Francisco Chronicle reports Monday (http://bit.ly/181CHKr) a father and his 6-year-old son first installed a wooden door to cover a hollow opening in the root of a tree outside the park’s de Young Museum in March.

The door crafted by Tony Powell stirred the delight of visitors who left notes and offerings for the little creatures who might be using the door. A few notes in a child’s scrawl asked if the tooth fairy is real and if elves can predict the future.

But when city park officials found out, they removed the door, saying its hinges damaged the tree.

The move sparked a small outcry, prompting city officials to replace the door with a temporary one that the Chronicle described as a “pale imitation of the original,” which was made of pine, coated in varnish and had a puny knob.

Powell put in a new one earlier this month that passes city inspection because it’s attached to a eucalyptus log — not a living tree.

Meanwhile, the replacement door that park officials said they would take down is still standing.

“We’re going to ask them if they’ll allow that to remain, since so many people still visit that door every day and not a lot of people know about the new one,” Powell said. “We’re hoping they can let the fairies keep that as a mailbox.”
