Having grown up in a very suburban community, we always locked our doors, windows, etc. Two to three deadbolts. Living on the the second floor or above was most desirable. Not easily accessible from the street. Lots of double and triple deckers, crime, etc. When going to school (junior and high schools) or walking to work, I carried a small pocket knife in my hand, blade open. I walked or boarded a bus no matter where I went and felt the need to protect myself.
Now, I live in what is considered a "rural" community. No public transportation, we have one stop-light in my village. I drive my kids pretty much everywhere. We're a small town but, geographically very spread out. Divided by the Cape Cod Canal. You can get there from here without a car. Lots of summer traffic.
Yet, I have several Level 3 sex offenders living within a few miles of my home. Does my hometown have more? Sure. But even one will set you on edge. Something I've noticed from the news and from the Center for Missing and Exploited Children: It appears as though just as many children are abducted from smaller, rural areas as larger suburban areas. Think about it. Abducting a child in a rural area is probably easier. Fewer, if any, witnesses. Try abducting a child on the streets of Boston or New York. Too many witnesses. One of the most publicized in my state was a young lady (16 or 17, as recall) named Molly Bish. A lifeguard at a local, small-town lake. Her remains were found a few years later, but the case is still unsolved.
I believe those of us who live in small towns have a false sense of security. We think we know everyone, but do we, really? When I first moved here, into a "family home", I couldn't believe how many people left their doors unlocked or didn't have deadbolts! My favorite saying at the time was; "I'm not putting any of you in charge of my childrens' personal security!"
I still have that mentality. No matter where we live, we must be on guard at all times. My kids call me "overprotective". I'd rather be called "names" by my kids, than be called by the coroner.
