How they will get to work, is hopefully via a comprehensive, environmentally-friendly mass transit system. I’d love to see a streamlined bullet train running down the center of I-5! There has been some talk of that, but don’t know what the latest is. Most likely it is just wider lanes on existing freeways though….
I tried to research the quantity of tech firms in SD last night, but could find no succinct data last night. I sent some emails out to friends, but so far no one has responded.
