I have this ongoing photo project to document (hopefully) all of the front-yard virgin mary statues and other religious icons that people have here in Somerville, Mass. I go street by street (on my bike of course) and keep track of where I've been on a map so I don't get any statues twice. Somerville is only four square miles, and I've covered about a third of it and am up to 196 pics. A few samples are here, and you can see the whole set
here.
