Thank you Sherri. I just found out the Sausalito Art Car by zaboo now even has its own facebook page!
Thank you Susan. I bicycled over the Golden Gate Bridge from San Francisco to Sausalito with my daughter 3 or 4 years ago and we saw this in one of the parking lots. Apparently it had already been there several years, as you can tell. More and more people add objects to it as the time passes. I wish I had taken more photos, but I was really only into point-and-shoot with a small digital compact in those days...
