After being featured in the September/October 2011 issue of Sierra, the Sierra Club's magazine, the above photograph of a pine tree that has grown around a child's bicycle has been making Internet rounds.
Berkeley Breathed, a one-time hero of mine, apparently created a children's book about this very "bike tree." I'll have to pick up a copy of Red Ranger Came Calling.
