I've seen the pedestals boxed up and it isn't them. I'm not really sure what it is, but I'm guessing maybe cables/wires? How do we know it was shipped from Tesla?
I agree that Tesla equipment arriving on site would be good news. I've definitely seen digging get started and then construction held up by not having the equipment available.
As to an earlier question from up thread, this site should be operational some time between a month and a year from now
There's been a ton of variance in how long these things take to be completed. There are many things that can cause long delays.
