Both are great, but I'm going to put in a blog plug for Tucson Bike Lawyer by Erik Ryberg, a local attorney that champions local bicyclists. I read it weekly, and I was recently blown away by a blog entry regarding Jose Rincon and what is called Ghost Bike --a method bicycling communities can use to commemorate bicyclists killed on the road at the location where the accident occurred.
I liked this concept, because it is certainly very much in tune with our Southern Arizona way of commemorating those who've passed--with little roadside markers and shrines. This, however, is a fitting way for the bicycling community to commemorate its own and draw attention to places in our city where people have been hit.
Besides Ghost Bike, look over Ryberg's blog. It's a good way to keep up on biking issues, and what is important to those driving two wheels, rather than four.
