I live in Austin Texas and had never even heard of Aubrey, so I looked it up. It's well north of Dallas, but in an area that is growing like wildfire. You might move there now and have it be a certain way, and in two years your taxes will have doubled and there won't be any more rural areas left.
I grew up not TOO far from there, and I can tell you that it's shockingly hot in the summer (but it's a dry heat, which is better than where I live now) and, well, to me it was "cold" in the winter, but it might be helpful to tell us where you live now, for comparison. North Texas, I think, has a decent amount of western riding, but again as DFW spreads north, you're going to be living in an exurb, not the country, if it's not already just an exurb.
Have you considered more west Texas, or Oklahoma?
Aubrey seems to be right north of Denton, which is a fairly liberal college town, or at least it used to be. There are two universities there, which are disproportionately large compared to the town itself. Do you like college students?
Small towns in Texas can be pretty conservative and even racist, xenophobic, homophobic, etc., if that sort of thing bothers you. If you are white, Christian, and very patriotic you will fit right in. But I'm not sure if the proximity to Denton might cancel that out. I guess you'd have to visit to know. Oh, and tornadoes. How do you feel about tornadoes? And lots of thunderstorms. And drought in the summer. But that might cut down on the flies?
On the plus side, it's probably not that expensive, for now. But with DFW growing all the time, I doubt it would stay cheap for long. Also there are nice sunsets. And being near DFW (although the traffic is terrible now) means you can get cheap flights to all over the world, that famous Dallas shopping (if you have the money and the desire), and lots of interesting places to eat.
Fort Worth has a lot of western events, if I recall correctly. And the Fort Worth area isn't as expensive, nor is it growing as quickly. You might find something to the west of Fort Worth that might be worth looking into. North and West of Fort Worth is pretty country, in my opinion. And definitely not as expensive.
I agree with
that Seattle has everything. Seattle is awesome, if you can handle the winters. We lived there for almost two years and will be moving back in a few years, hopefully.
