 You know, I look at cyclist data all the time, but when I made a map of the people who were in crashes with helmets and without helmets, I started seeing a lot of spatial trends that I never noticed before. So, for example, 4th Street between Paseo del Norte and downtown Albuquerque, there's really no crashes that anybody was wearing a helmet for. It's a huge line along 4th Street of cyclist crashes without helmets.
