Those cone-shaped loads are very common around SpaceX.
What's curious is an Amazon distribution warehouse closed a year or so ago nearby and it's obvious that something SpaceX related is happening there. There's no signage on the building and the security has been increased since Amazon left. I don't think SpaceX rented the property just to have more employee parking. It's a very odd situation. I'm sensitive to 'stealth' buildings and this one is pretty obvious.
(Don't get me going on the building where they (not SpaceX-related) built a second wall just inside the exterior wall for some reason. It's a modern building that fits in to the modern industrial/commercial park it's located. There were a number of weird things about it but it has never had any sort of signage or indication of anyone working there. I suspect a tunnel from another building in the area.... oh, it's also beautifully maintained.
Lots of stealth building around here and I pass by what used to be ((still could be for all I know)) a Northrup lab. It's big and there's a dedicated power line that travels several miles that goes to it. Northrup moved away and sold a lot of property but this facility remains with no signage and people working there. It's an odd place.)
Sorry for the digression...
