I did read Tonya's article, and that's a scary event. I also have those door sticks that go under the knob and down to the floor. They work and make me feel safer. Windows are probably the easiest way to get in. Mine go almost to the floor, so I ensure they are locked! Good advice. I won't even walk in the park alone. I've heard too many nightmare stories to do it, and I hold pepper spray when walking with a friend!
