These are the latest incarnations of  what has been a constant source of surprise and delight over the last several months to those of us who walk this part of Altadena.It appears that there is more than one person behind these creations. As I took these photos I met the man who said he had begun it, but that others had “taken it to a whole new level”.A couple of weeks ago I saw one of my Maiden Lane neighbors constructing a new one. How many others are involved I wonder? This is one of those things that makes us say to ourselves, “Don’t you just love Altadena?” Check out the little grey “bridge”!
