When you have time, I hope you'll add more to the entry's opening paragraphs re. the history and impact of night skiing. For instance, night skiing was probably independently "invented" several times. I have a brochure that shows that Bousquet Ski Grounds (the area's name back then) in Pittsfield MA had night skiing in 1940, and night skiing may have occurred there even before that. Your Wikipedia page mentions Summit West in WA, which Webb Moffett acquired in 1942, according to another Wiki page.
Night skiing arrived well before snowmaking. It made it possible to ski during weekday evenings instead of confining skiing to weekends. Often a Monday or Tuesday snowfall would disappear by Saturday morning, relegating so many would-be skiers to shoveling only rather than shoveling and then skiing. I also think of the impact of the availability of night skiing on popularizing the sport through school clubs and racing teams.

Thanks Woody, that's a great idea. I will! (at some point )
