Interesting topic. Im sitting in the office in the Virgin Islands(where there arent any) waiting for it to get dark so i can fly some folks out to Peter Island (www.peterisland.com) They are on vacation and Im just going to go scare myself for fun......Kidding
It does get very dark down here in the Islands and this company Bell 206L just loves daylight.
Over the years I have found that the one thing that has kept me from balling one up at night is to take things a lot slower and not to make steep turns. Over water, no moon and Zero Horizon can be real fun...Luckily there is a moon out tonight.....
Stay Safe
