A couple of stations closed recently in Connecticut; one in Southington and one in Waterford. Those are the ones that I know of. I don't know what the contractors do with the old signage, but if anyone is interested in it, maybe they can reach out to them.

All the Hess station around here(Saratoga Springs) have changed there names, to I think Speedway. They where the last stations around here using the ECO air meters.

Speedway is correct, Bob. The rebranding process started about four years ago:
