Its not that hard you just have to spend the time. Go to the target neighborhoods after school hours during the week and see what is going on (its tough this time of year as it gets dark at 5). Head over on a weekend late morning/early afternoon with your family, park your car and walk around. Talk to people you see on the streets (if there are any). If you see people out and about that is a good sign. If you dont see anyone out and about you’ll know people keep more to themselves. Even though neighbors change the general population of a neighborhood is more consistent.
