I think the area around Reston / Dulles would make a great pick. The Silver Line will be finished soon, and there is plenty of room to build it up in the style of Arlington's Orange Line or Old Town's Blue. Dulles being 10 minutes away would be a huge advantage, especially compared to Denver where the airport is a long ways from both the tech corridor and the Boulder area. Traffic is still a nightmare and housing costs are pretty bad compared to most cities, but there is a lot of tech talent here and wages seem lower than NY, Seattle, and the Bay Area. NOVA is liberal, but Virginia is business friendly, unlike DC and MD. There is already the big NE Virginia AWS here, and I'm pretty sure most of the governments and intel communities AWS infrastructure is also housed close by.
