Some time ago I shared some work of Blake Andrews here. Blake is also a participant in photographic grid projects. The basic idea about a grid project is to divide the map of an area into squares, and then systematically go make pictures in these squares. Ideally multiple photographer participate, thus creating a body of work that varies in style.
When he lived Portland, Blake Andrews participated in the Portland Grid Project. And after moving to Eugene, he started a Eugene Grid Project. There is a link on his site here. But unfortunately it points to an unknown web address.
The vernacularity of the pictures produced in these projects is refreshing and inspiring.
