Funny you post winter is best time to fly at night.
I would like to fly nights but the geography were I live is not good for that. Airport (PAJN) is open 24 hours controlled 6:00am to 10:00pm with runway lights that are turned on by radio.
Airport is at sea level and mountains rise to 4 to 10 thousand feet all the way down the coast. South East Alaska has unforgiving terrain. No real place to ditch if you have to, rocky shore lines, and steep mountain's.
Summer on a full moon is best here. Daylight 18+ hours, Winter OK with full moon, but it rains/snows so much that there is normally a cloud layer that hangs close to mountain's.
Enjoy your night flying it is few and far between were I live.
