The movie history of Petaluma is wide, LB Tree is an old stump that was pictured, in its full canopied glory in the 80's movie, Explorers. Just down the trail from LB Tree, is another cluster of trees with a great view of the hostoric downtown Petaluma where American Graffiti was filmed. This cache is hidden in plain site, but "naturally hidden", enjoy. No tree climing required, please place back where you found it.
