They tried that - North Dallas was a rising star as a tech magnet. Nortel/Enron/Worldcom ( and dare I say Cisco? ) killed it dead. There's a modest smattering of tech left there, but it's all very weak and thready in pulse. Perhaps also ditto Atlanta. I don't know what is holding Dallas up now.

I won't go to the Valley, and it's been worth it. I'm north of Houston right now. Had a chance at a really compelling Valley gig last year, with an awesome boss and turned it down purely because of location.

We as a culture have traded "making a comfortable living" for "making a killing".
