A few years ago the mid-sized town I live in had the highest murder rate per capita in the country. I too am very aware of my surroundings when I am alone...either on my bike or out shopping, etc. But sometimes I think we are scaring ourselves too much; seeing crime and criminals in every shadow. Case in point: The other day DH goes to Wal-Mart to pick something up. He was in there about 15 minutes. He starts walking back to the car and is fishing for his keys and can't find them. He then thinks, "Damn, I locked them in the car." He gets to the car...the car is running with the door unlocked. He must have been distracted (seriously!) and just got out and walked into the store. Even in a town with it's share of crime nobody took off in the car.

I agree - know how to protect yourself. So, be aware but don't live in fear.
