Interesting tidbit:

The execs who showed me around today said they chose the [Prineville, OR] site based on an exhaustive search for the perfect combination of low-seismic risks, cooler and mostly dry weather, access to power and Internet trunk lines (Prineville is an old railroad community, and fiber lines run under the railroads here) and a variety of other factors including low tax rates and friendly climate to business, etc.
