I drove thru this service center on my way south yesterday. This was the first time I stopped in after the sun was down. I noticed something curious that was either new or not apparent during the daytime visits. The cones were still there blocking people from parking at the stalls and the pedestals were still covered with the white Tesla bags, but at night I could see through the coverings that the pedestals were lit up. I didn't have the nerve to move the cone, back in, pull the bag off the pedestal and try to see if they would actually work, but it looks like everything is ready to go. I guess they are just waiting on some final inspection or approvals.
If I go by again at night I will try to get a pic.
