I don’t do any rode biking, but I was thinking about caring a small light firearm in my camelback just in case I ran into a wildlife situations in CO. I know it wouldn’t do anything to a bear, but its good for scaring off mountain lions and maybe any brawley rednecks that slam thier brakes in my path, especially if I have my son with me. It would definitly have to be in a serious life threatening situation though.
