As a fellow former resident of the county-spanning Westlake area, I can tell you that even the people that live there don't know where they live. I was debating with a friend of mine just the other day, and her and her mom couldn't even agree what city they lived in. Then I looked it up on the map, and different maps gave different answers. And they keep building new houses, so who the hell knows which tax jurisdiction each individual house is in? The people that live in them can't even keep track!
