I agree with the night flying is FUN contingent! Also, that even 1 hour of night is preferrable to none, and that 3 hours of washed out windscreens when flying east or west is a real downer. Just a little tweak on the clouds and wind would be good as well (maybe a 5 or 10 knot wind and a few more clouds). Perma daylight: BAD!
BRING BACK THE NIGHT!!!
