I spoke to them again Monday afternoon and they said their company has bids in for Las Vegas and Denton, TX, but we didn't discuss any other locations. He did say that they have built SC's in other states, and the contract decisions are a complicated process with Tesla. The award for LV is expected this week.
I suspect that they need to sign the contractor before they can finalize the building permit. That could explain why the Denton, TX building permit has been in suspended animation for so long.
