We don't want to hang around. Living in the sticks is also a boon when it comes to staff retention. One of the reasons that the army put our team in Fort Huachuca is that it had developers stationed in Washington, DC and they'd all left within six months for better paying jobs. In Silicon Valley, staff turnover works out at just a few months. Swimming pools and fast cars aren't the only reason that Ephibian manages to attract the technical elite.
