North Carolina has the 'triangle' area which has seen huge growth for many years. Texas has Austin, which is probably the closest to SV of any place I've ever been. It looks so much like SV you could probably confuse the two in pictures
My bet is on the Raleigh-Durham triangle, Atlanta, or Austin.
Same. Except I'm not as optimistic about Atlanta because the state is mostly poor and it's farther from the huge cities on the upper east coast. NC and Texas are both booming state-wide and have 'world cities' in reasonable driving distance.
