New road sign on the way to our main dark site (Cherry Springs PA, it's on the ridge there in the distance, elev. 700 m a.s.l.). Incidentally, you see some clouds in the picture, but the night turned out beautifully - completely clear from the end of the astronomical twilight on, SQM 21.82, seeing 1".
