Tesla Superchargers have been sighted at the Montgomery Promenade in front of the under construction Whole Foods on 206 next to the Princeton Airport. I believe the site plan calls for 12 chargers. Saw the cabinets last week and they looked right but at least two V4 chargers are now visible.
This is approximately 300 yards south on 206 of the site on Tesla.com that was voted in a few quarters ago.
