I have enjoyed reading all the viewpoints here today...
I will add that, as others have stated, safety is obviously important...but if you carry yourself as a victim, you will become one. Predators are looking for the weak to take advantage of....
I always answer my door, as I want people to know that I'm not scared. I carry myself the same way when I'm out and about. I pride myself on being someone that looks like she doesn't take any crap, lol. Don't get me wrong, I'm extremely friendly, just also extremely street smart.
By and large, this area is extremely safe. I cringe when people say the area is bad, as I assume that they have probably not had the pleasure of spending time in an real "bad" area. I have, I grew up in Alief, an actual bad area. Atascocita is a 180 from that area of town.
