Crash? What counties do you consider a "bellwether" for market?

[Jay G.]

I'm a market data guy.  Let's do a little (possibly insightful) exercise here....  what counties do you consider a bellweather for market conditions? That is, the county that is most likely to be the "canary in the coal mine" so to speak, to determine when the market may indeed be rolling over, rather than just cyclically cooling off.   If we can get a consensus on a few counties I'll crunch data and report the results.
