Hey I live in the county with the second most per-capita permits to carry a concealed weapon county in the US! I never carry a gun and ride through some 7 (on a US scale of 10), worse areas in the city. Only slighly more likely to die by gun then car. You'd probably do better to wear your bike helmet in the car! Dont forget some of those gun deaths where caused by the victoms gun.
