like i said dont be so paranoid that bad things will happen.the chances are slim. just take a bottle of water and and maybe a pill or two. if your that worried about something bad happening then dont go walking ,choose another location to walk, or <img src="/images/graemlins/smile.gif" alt="" /> (my favorite) take a self defense class.
use your brain and dont worry nothing will happen.
Like someone once said "There's a big difference between prepared and paranoid."
