It's been said before, but bears repeating....
Where you live is less important than how you've managed your surroundings. For example: do you know your neighbors? Do you know whom you can depend on in an emergency (including "help, I fell and broke my leg" type emergencies)? Do you have a neighborhood plan for dealing with emergencies? If not, you are less secure than you could be, regardless of where you live.
We have a place in Harris County, suburb of Houston. We know our neighbors on either side, across from us, and several houses down on one side. All the rest we know at least to say "hi" to and have some sense of who they are and what they're like. I know who owns guns (most everybody) and I'd not hesitate a second in getting them together for a mutual neighborhood watch in case another Rita takes a bit more westerly turn and lands on us. The old saying "there is safety in numbers" is correct... if you have a number of people providing security that is better than if it is just you. After all, you have to sleep sometime
We also own a ranch somewhat north of the OP's place, outside Llano. The neighbors there are few and far between, and we don't yet know them (new purchase in the last couple of months). But we will. It's up there on the "to do" list. In both places, we bought for "what we like" rather than "maximum security". I refuse to live in a bunker or a bomb shelter. I'll do what I can within reason to ensure that I am safe where I am, and that includes electronic alarm systems and cameras if need be; but no islands in the pacific with mines, thanks.
Point is: wherever you live, be proactive without screwing up your quality of life. Remember, it's software, not hardware, that matters.
