gcam needed an init at checkout.

The night started with snow, fog, rain, thunder!, dust, more fog, but cleared around 22:30. The humidity was still a big high but was staying under 80%. However, humidity went over 85% a little after midnight and we had to close. It cleared up again after 2 hours and it was clear the rest of the night.
